STR3A461HL
Description
The STR3A46x HL/HDL series are power ICs for switching power supplies, incorporating a power MOSFET and a current mode PWM controller IC.
To enhance efficiency in all load ranges, the IC automatically shifts its operation to the green mode or burst oscillation mode, depending on the load. The product achieves high cost-performance power supply systems with few external ponents.
Features
- Bare Lead Frame: Pb-free (Ro HS pliant)
- 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 Reduction
- Current Mode Type PWM Control
- Soft Start Function
- Automatic Standby Function No Load Power Consumption < 15m W
- Operation Mode Normal Operation ----------------------------PWM Mode Light Load Operation----------------------- Green-Mode Standby -------------------------- Burst Oscillation Mode
- Random Switching Function
- Slope...
