LDO VS DC to DC Converter11 March 2022
Hello everyone, I am Rose. Today I will introduce the differences between LDO and DC to DC Converter to you. LDO stands for low dropout regulator, which is a low dropout linear regulator.A DC/DC converter is a voltage converter that converts an input voltage and efficiently outputs a fixed voltage.
Automotive Chips Rose Across the Board!11 March 2022
According to the financial report, the core chip of the body electronic stability system produced by STMicroelectronics used to cost only 20 yuan to buy. However, due to shortages and upselling, these chips have now been speculated to be nearly 3,000 yuan and are priced out of the market.
Ceramic Capacitor Basis: Definition, Types and Parameters10 March 2022
Hello everyone, I am Rose. Today I will introduce ceramic capacitor to you. Ceramic capacitors are also called ceramic capacitors or monolithic capacitors. As the name suggests, a ceramic capacitor is a capacitor whose dielectric material is ceramic.
MediaTek, Qualcomm Announce Joining Russia Sanctions10 March 2022
Russia and Ukraine are in a fierce war. Various countries around the world have sanctioned Russia, and many companies have responded. After TSMC announced a ban on exports to Russia in compliance with U.S. trade agreements, Taiwan's IC design leader MediaTek and U.S. Qualcomm followed suit and banned exports of chips to Russia.

Hello everyone, I am Rose. Welcome to the new post today. Today I will introduce 5 classical power supply circuits to you. They are: power supply, switching power supply, DC-DC power supply, charging circuit and constant current source.
When Designing a Power Supply, How to Consider the Selection of Topology?07 March 2022
Hello everyone, I am Rose. Today I will tell you how to select power topology and the characteristics of each topology.
EMC can also observe the waveform with an oscilloscope?04 March 2022
What's the difference between EMC's near field and distant field? Let's talk about it together today! EMC, also known as electromagnetic compatibility, is a complete assessment of an electronic product's electromagnetic field interference (EMI) and anti-interference capabilities (EMS), and is one of the most important indicators of product quality.
Aluminum Electrolytic Capacitor Basis: Definition, Characteristics and Life03 March 2022
Hello everyone, I am Rose. Welcome to the new post today. Aluminum electrolytic capacitors are made of an aluminum cylinder as the negative electrode, which is filled with liquid electrolyte and inserted into a bent aluminum strip as the positive electrode.
How to Choose MOSFET for Switching Power Supply?02 March 2022
A metal-oxide semiconductor field-effect transistor (MOSFET) is a field-effect transistor that can be widely used in analog circuits and digital circuits.This article will help you to select MOSFET for switching power supply.
AC Contactor: What is Self-Locking?01 March 2022
AC contactors often use three arc extinguishing methods: double-break electric arc extinguishing, longitudinal seam arc extinguishing and grid arc extinguishing. It is used to eliminate the arc generated by the moving and static contacts during the opening and closing process.This article mainly introduce the principle of AC Contactor self-locking.
AC/DC, DC/DC Converter Fundamental Guide28 February 2022
Hello everyone, I am Rose. Welcome to the new post today. This article mainly introduce the definition of AC and DC, AC/DC Converter as well as DC/DC converter.
Switching Regulator Noise: Comprehensive Understanding and Analysis26 February 2022
Switching ripple, broadband noise, and high-frequency spikes are all types of noise found in switching regulators, as described in this article. With addition, the switching regulator PSRR in relation to input noise rejection will be discussed and analyzed in this article. It is critical to have a solid grasp of switching regulator noise when building low noise switching regulators in order to minimize LDO post-regulators and enhance power converter efficiency, solution size, and design cost.
