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

・Low Thermal Resistance Package・Improving circuit efficiency (Since the step drive control can keep VRM of secondary rectification diodes low, the circuit efficiency can be improved by low VF.)・Current Mode Type PWM Control・Soft Start Function・Auto Standby Function No Load Power Consumption < 15mW・Operation Mode Normal Operation: PWM Mode Light Load Operation: Green-Mode Standby: Burst Oscillation Mode・Random Switching Function・Slope Compensation Function・Leading Edge Blanking Function・Bias Assist Function・Protections Overcurrent Protection (OCP): Pulse-by-Pulse Overload Protection (OLP): Auto-restart Overvoltage Protection (OVP): Auto-restart Thermal Shutdown (TSD): Auto-restart with hysteresis
