Description

The SC4520 is a current mode switching regulator with an integrated switch and an adjustable frequency with enable function. The integrated switch allows for cost effective, low power solutions with a peak switch current of 3 amps. An adjustable high frequency of 100kHz to 600kHz provides for fast dynamic response and instantaneous duty cycle adjustment as the input varies, making the device ideal for CPE applications where the input is a wall plug power. Low shutdown current also makes the this device an excellent choice for portable applications where conserving battery life is of prime concern.
