SC4521 Datasheet (Semtech Corporation) - 3A Step-Down Switching Regulator

SC4521, 3A Step-Down Switching Regulator

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
