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 component counts, and high performance-to-cost power supply.
