Overview
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 accomplished 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 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) ● 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 ...
