Sanken Electric Co., Ltd. STR3A453D | Demoboard DEJ0007

Beschreibung

The STR3A453D is a power IC for switching power supplies, incorporating a power MOSFET and current-mode PWM controller IC.The product achieves low power consumption and low standby power by including a startup circuit and a standby function that automatically switch operation modes – PWM mode in normal operation and burst-oscillation mode under light-load conditions. Its enhanced protection functions also enable higher cost-effective power supply systems with few external components.

Eigenschaften
