STR3A453
Overview
The STR3A400 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.
- 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
- Automatic 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
