Overview

3A Step-Down Switching Regulator with Programmable Soft Start POWER MANAGEMENT Description The SC4521 is a current mode switching regulator with an integrated switch, operating at 600kHz with programmable soft start and enable functions.
The integrated switch allows for cost effective low power solutions (peak switch current 3 amps).
High frequency operation allows for very small passive components.
Current mode operation allows for fast dynamic response and instantaneous duty cycle adjustment as the input varies (ideal for CPE applications where the input is a com wall plug power).
The low shutdown current makes it ideal for portable applications where battery life is import...
