STR3A155 Datasheet Off-line Pwm Controllers

Manufacturer: Sanken

Overview: Off-Line PWM Controllers with Integrated Power MOSFET STR3A100 Series.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

s The STR3A100 series are power ICs for switching power supplies, incorporating a 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.

The product achieves high cost-performance power supply systems with few external components.
