Secondary Side Post Regulator for AC/DC and DC/DC Multiple Output Converters
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
voltage (VCC) range and up to a 75 V drive voltage (VC).
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 SO package.
