CS5101/D

CS5101

Secondary Side Post

Regulator for AC/DC and

DC/DC Multiple Output

Converters

The CS5101 is a bipolar monolithic secondary side post regulator

(SSPR) which provides tight regulation of multiple output voltages in

AC/DC or DC/DC converters. Leading edge pulse width modulation

is used with the CS5101.

The CS5101 is designed to operate over an 8.0 V to 45 V supply

The CS5101 features include a totem pole output with 1.5 A peak

output current capability, externally programmable overcurrent

protection, an on chip 2.0% precision 5.0 V reference, internally

compensated error amplifier, externally synchronized switching

frequency, and a power switch drain voltage monitor. It is available in

a 14 lead plastic DIP or a 16 lead wide body SOIC package.
