Off-Line PRC Controllers with Integrated Power MOSFET
STR-A6100 Series
General Descriptions
The STR-A6100 series are power ICs for switching power supplies, incorporating a MOSFET and a current mode PRC controller IC.
PRC (Pulse Ratio Control) controls on-time with fixed off-time.
The IC includes a startup circuit and a standby function to achieve the low standby power. The rich set of protection Features helps to realize low ponent counts, and high performance-to-cost power supply.
