STR-A6159M
Package : DIP8 (Pin 6 Removed)
RoHS : YES
The STR-A6100 series are power ICs for switching power supplies, incorporating a MOSFET and a current mode PRC controll 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.
