Off-Line PWM Controllers with Integrated Power
MOSFET
STR3A400HDL Series
Data Sheet
Description
The STR3A400HDL 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.
The product achieves high costperformance power supply systems with few external components.
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) ● Noise R...
