16 - Number of Outputs1
- Output Voltage
Output voltage is a crucial parameter in electronic components that refers to the voltage level produced by the component as a result of its operation. It represents the electrical potential difference between the output terminal of the component and a reference point, typically ground. The output voltage is a key factor in determining the performance and functionality of the component, as it dictates the level of voltage that will be delivered to the connected circuit or load. It is often specified in datasheets and technical specifications to ensure compatibility and proper functioning within a given system.
46V - Max Supply Voltage
In general, the absolute maximum common-mode voltage is VEE-0.3V and VCC+0.3V, but for products without a protection element at the VCC side, voltages up to the absolute maximum rated supply voltage (i.e. VEE+36V) can be supplied, regardless of supply voltage.
46V - Min Supply Voltage
The minimum supply voltage (V min ) is explored for sequential logic circuits by statistically simulating the impact of within-die process variations and gate-dielectric soft breakdown on data retention and hold time.
9V - Output Current
The rated output current is the maximum load current that a power supply can provide at a specified ambient temperature. A power supply can never provide more current that it's rated output current unless there is a fault, such as short circuit at the load.
3A - Topology
In the context of electronic components, "topology" refers to the arrangement or configuration of the components within a circuit or system. It defines how the components are connected to each other and how signals flow between them. The choice of topology can significantly impact the performance, efficiency, and functionality of the electronic system. Common topologies include series, parallel, star, mesh, and hybrid configurations, each with its own advantages and limitations. Designers carefully select the appropriate topology based on the specific requirements of the circuit to achieve the desired performance and functionality.
Step-Down (Buck) - Min Input Voltage
The parameter "Min Input Voltage" in electronic components refers to the minimum voltage level that must be applied to the component for it to operate within its specified parameters. This value is crucial as providing a voltage below this minimum threshold may result in the component malfunctioning or not functioning at all. It is important to adhere to the specified minimum input voltage to ensure the proper operation and longevity of the electronic component. Failure to meet this requirement may lead to potential damage to the component or the overall system in which it is used.
9V - Max Input Voltage
Max Input Voltage refers to the maximum voltage level that an electronic component can safely handle without getting damaged. This parameter is crucial for ensuring the proper functioning and longevity of the component. Exceeding the specified maximum input voltage can lead to overheating, electrical breakdown, or permanent damage to the component. It is important to carefully adhere to the manufacturer's guidelines regarding the maximum input voltage to prevent any potential issues and maintain the reliability of the electronic device.
46V - Output Current per Channel
Output Current per Channel is a specification commonly found in electronic components such as amplifiers, audio interfaces, and power supplies. It refers to the maximum amount of electrical current that can be delivered by each individual output channel of the component. This parameter is important because it determines the capacity of the component to drive connected devices or loads. A higher output current per channel means the component can deliver more power to connected devices, while a lower output current may limit the performance or functionality of the component in certain applications. It is crucial to consider the output current per channel when selecting electronic components to ensure they can meet the power requirements of the intended system or setup.
3A - Dimming
Dimming is a feature in electronic components, such as LED lights or display screens, that allows the user to adjust the brightness level of the device. It is a method of controlling the amount of light output by the component, typically by varying the voltage or current supplied to it. Dimming can be achieved through various techniques, such as pulse-width modulation (PWM) or analog dimming. This feature is commonly used to save energy, create ambiance, or enhance visual comfort in different applications.
PWM - Number of Segments3
- Multiplexed Display Capability
Multiplexed Display Capability refers to the ability of an electronic component or system to control multiple display elements using fewer input/output lines. This is achieved by rapidly switching between different displays or segments, allowing for efficient communication and reduced wiring complexity. In multiplexed systems, each display is activated sequentially, creating the illusion of simultaneous display to the user. This capability is commonly utilized in devices like LED matrices and LCD screens to enhance functionality while conserving space and resources.
NO - Height750μm
- Length4mm
- Width4mm
- REACH SVHC
The parameter "REACH SVHC" in electronic components refers to the compliance with the Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) regulation regarding Substances of Very High Concern (SVHC). SVHCs are substances that may have serious effects on human health or the environment, and their use is regulated under REACH to ensure their safe handling and minimize their impact.Manufacturers of electronic components need to declare if their products contain any SVHCs above a certain threshold concentration and provide information on the safe use of these substances. This information allows customers to make informed decisions about the potential risks associated with using the components and take appropriate measures to mitigate any hazards.Ensuring compliance with REACH SVHC requirements is essential for electronics manufacturers to meet regulatory standards, protect human health and the environment, and maintain transparency in their supply chain. It also demonstrates a commitment to sustainability and responsible manufacturing practices in the electronics industry.
No SVHC - Radiation Hardening
Radiation hardening is the process of making electronic components and circuits resistant to damage or malfunction caused by high levels of ionizing radiation, especially for environments in outer space (especially beyond the low Earth orbit), around nuclear reactors and particle accelerators, or during nuclear accidents or nuclear warfare.
No - RoHS Status
RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.

What is A6210?
The A6210 is a buck regulator that uses valley current-mode control. This control scheme allows very short switch on-times to be achieved, making it ideal for applications that require high switching frequencies combined with high input voltages and low output LED span voltages.
How to use A6210?
The A6210 is a regulating LED driver that utilizes valley current mode control. The on-time is set by the amount of current that flows into the TON pin. This is determined by the value of the TON resistor chosen (R1 in the Functional Block diagram) and the magnitude of the input voltage, VIN. Under a specific set of conditions, and on-time can be set that then dictates the switching frequency. This switching frequency remains reasonably constant throughout load and line conditions as the on-time varies inversely with the input voltage.
