Description
The STR3A400 series are power ICs for switching power supplies, incorporating a MOSFET and a current mode PWM controller IC.
Features
- 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 ---------------------------.
