Datasheet Summary
Off-Line PWM Controllers with Integrated Power MOSFET
STR3A400 Series
Data Sheet
Description
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 acplished by the automatic switching between the PWM operation in normal operation and the burst-oscillation under light load conditions. The product achieves high cost-performance power supply systems with few external ponents.
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...
