The LM2854 PowerWise® SIMPLE SWITCHER® buck regulator evaluation board is a 500 kHz step-down voltage regulator capable of driving from 0A to 4A load current with excellent power conversion efficiency. The LM2854 TSSOP-16 evaluation board is designed to accept an input voltage rail between 2.95V and 5.5V and deliver a fixed and highly accurate output voltage of 1.2V. The output voltage level can be changed by modification of one feedback resistor. The device allows external soft-start and monotonical, glitch free into a pre-biased start. Lossless cycle-by-cycle peak current limit is used to protect the load from an overcurrent or short-circuit fault, and an enable comparator permits system sequencing or increase of the input UVLO above the nominal 2.7V level.
