Texas Instruments TPS92201AEVM Evaluation Module

Texas Instruments TPS92201AEVM Evaluation Module evaluates the performance of the TPS92201A synchronous buck switching regulator designed for LED driver applications. This module operates from 2.2V to 5.5V input voltage range and delivers up to 95% efficiency. The TPS92201AEVM is adjusted for a 0.5A default output current at 3.3V/100% duty cycle PWM input. This module features 1μA shutdown current, 1.5MHz switching frequency, 100mV feedback regulation voltage, and 1% to 100% analog dimming. The TPS92201AEVM evaluation module is used in video doorbells, smart home cameras, IP cameras, flashlights, and rider accessories.
