Adjustable Switching Frequency

POWER MANAGEMENT

Features

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.

Wide operating voltage range: 4.4V to 24V

Integrated 3 Amp switch

100kHz to 600kHz adjustable frequency operation

Current mode control

Precision enable threshold

SO-8 EDP package. Lead-free product, fully WEEE

and RoHS compliant
