The TPS92201AEVM provides an LED driver based on the TPS92201A buck regulator and is designed to operate with an input voltage in the range of 2.2 V to 5.5 V. The EVM is set up for a default output current of 0.5 A at 3.3 V and 100% duty cycle PWM input. The TPS92201 helps provide high efficiency, wide dimming range, good line regulation, and low output ripple LED driver.
