Off-Line PWM Controllers with Integrated Power MOSFET
STR-W6000S Series
General Descriptions
Package
The STR-W6000S series are power ICs for switching
power supplies, incorporating a MOSFET and a current
mode PWM controller IC.
TO220F-6L
The low standby power is accomplished by the
automatic switching between the PWM operation in
normal operation and the burst-oscillation under light
load conditions. The product achieves high
cost-performance power supply systems with few
external components.

* 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.
