CS5101
Secondary Side Post Regulator for AC/DC
and DC/DC Multiple Output Converters
Description
Features
The CS5101 is a bipolar monolithic
secondary side post regulator
(SSPR) which provides tight regula-
tion of multiple output voltages in
AC-DC or DC-DC converters.
Leading edge pulse width modula-
tion is used with the CS5101.
The CS5101 is designed to operate
over an 8V to 45V supply voltage
(VCC) range and up to a 75V drive
voltage (VC).
The CS5101 features include a totem
pole output with 1.5A peak output
current capability, externally pro-
grammable overcurrent protection,
an on chip 2% precision 5V refer-
ence, 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.
