Quasi-Resonant Controllers with Integrated Power MOSFET
STR-Y6700 Series
General Descriptions
Package
The STR-Y6700 series are power ICs for switching TO220F-7L
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 quasi-resonant
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
s supply systems with few external components.
