The Texas Instruments TPS5403EVM evaluation module (EVM) helps designers evaluate the performance of the TPS5403 non-synchronous step-down regulator with integrated MOSFET. The TPS5403 is designed to provide a fixed 3.3-V output and 1.7-A continuous current with an operational range of 4.5 V to 28 V and an external set switching frequency ranging from 50 kHz to 1.1 MHz.
