STR4A100 Datasheet (Sanken) - Off-Line PWM Controllers

STR4A100, Off-Line PWM Controllers

The STR4A100 series are power ICs for switching power supplies, incorporating a sense MOSFET and a current mode PWM controller IC.

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.
