The STR-V100 series are comprise an integrated power MOSFET and a controller IC with a current mode and PRC* control for switching power supply applications.
* PRC (Pulse Ratio Control)---the control method for OFF-time fixed and ON time controlled (Sanken’s designation)
The SIP8L full mold package of low-profile and with creeping distance between high and low voltage of 4mm or longer (lead pin on Printed Circuit Board, PCB).
A startup circuit and a standby function are incorporated in the control circuit. Thereby, requirements for low power consumption and low standby power can be achieved. The product easily achieves high cost-performance power supply system with few external components and enhanced protection functions.
