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 SOIC package.
Features
• 1.5 A Peak Output (Grounded Totem Pole)
• 8.0 V to 75 V Gate Drive Voltage
• 8.0 V to 45 V Supply Voltage
• 300 ns Propagation Delay
• 1.0% Error Amplifier Reference Voltage
• Lossless Turn On and Turn Off
• Sleep Mode: < 100 mA
• Overcurrent Protection with Dedicated Differential Amp
• Synchronization to External Clock
• External Power Switch Drain Voltage Monitor
• Pb−Free Packages are Available*
