STMicroelectronics STEVAL-ISA069V1Power Management IC Development Tools ST1S31 3A 1.5 MHz Switching Reg BRD

The STMicroelectronics STEVAL-ISA069V1 is a demonstration board that features the ST1S31, a 3 A / 1.5 MHz step-down synchronous switching regulator, an audio amplifier, and a USB charger. The ST1S31 is a high-efficiency, low-noise, and low-EMI synchronous buck regulator that is capable of delivering up to 3 A of output current. It also features a wide input voltage range of 4.5 V to 28 V and a wide output voltage range of 0.8 V to 5.5 V. The audio amplifier is a Class-D amplifier with a maximum output power of 2 W and a THD+N of 0.1%. The USB charger is a USB 2.0 compliant charger with a maximum output current of 1.5 A. The STEVAL-ISA069V1 is an ideal platform for evaluating the performance of the ST1S31, the audio amplifier, and the USB charger.
