Description
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.
Features
- Current Mode Type PWM Control.
- Auto Standby Function
No Load Power Consumption < 10 mW.
- Operation Mode
Normal Operation: PWM Mode Standby : Burst Oscillation Mode.
- Random Switching Function.
- Slope Compensation Function.
- Leading Edge Blanking Function.
- Bias Assist Function.
- Soft Start Function.
- Protections.
- Overcurrent Protection (OCP) : Pulse-by-Pulse, built-in compensation circuit to minimize OCP point variation on AC input voltage.
