Secondary Side Post Regulator for AC/DC and DC/DC Multiple Output Converters
ON Semiconductor Corp
Description
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.
