STR-Y6766

Package Image

Package:TO220F-7L

The STR-Y6700 series are power ICs for switching power supplies, incorporating a MOSFET and a quasi-resonant controller IC.
Including an auto standby function in the controller, the product achieves the low standby power by the automatic switching between the PWM operation in normal operation, one bottom-skip operation under medium to light load conditions and the burst-oscillation under light load conditions. The product achieves high cost-performance power supply systems with few external components.
