Quasi-Resonant Controllers with Integrated Power MOSFET
STR-Y6700 Series
General Descriptions
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.
Features
Multi-mode Control
The optimum operation depending on load conditions
is changed automatically and is achieved high
efficiency operation across the full range of loads.
Operation Mode
Normal load -------------------------Quasi-resonant mode
Medium to light load -------------One bottom-skip mode
Light load -------------------------- Burst oscillation mode
(Auto standby function)
No load power consumption
PIN < 30 mW (100VAC)
PIN < 50 mW (230VAC)
Leading Edge Blanking Function
Bias Assist Function
Built-in startup circuit reduces
Protections
Overcurrent Protection 1 (OCP1): Pulse-by-Pulse, with
Input Compensation Function
Overcurrent Protection 2 (OCP2)(1): Latched shutdown
Overload Protection (OLP): Latched shutdown
Overvoltage Protection (OVP): Latched shutdown
Thermal Shutdown Protection (TSD): Latched shutdown
(1) Products with the last letter "A" don’t have the
OCP2 function.

(2) The output power is actual continues power that is measured at
50 °C ambient. The peak output power can be 120 to 140 % of
the value stated here. Core size, ON Duty, and thermal design
affect the output power. It may be less than the value stated here.
