Description
Off-Line PWM Controllers with Integrated Power MOSFET STR3A400 Series Data Sheet .
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 N
Applications
* AC/DC adapter
* White goods
