STR6A161HVD
Description
The STR6A100x V/x VD series are power ICs for switching power supplies, incorporating a MOSFET and a current mode PWM controller IC.
The operating mode of the IC automatically changes to green-mode or burst oscillation mode according to load in order to improve the all load efficiency. The product achieves high cost-performance power supply systems with few external ponents.
Features
- 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
