AC-DC Converter ICs with Adjustable Standby Operating Point
September 29, 2017 by Paul Shepard
The STR6A100MV/HVD series from Sanken 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 components.
Applications are expected to include:
- White Goods
- Office Automation Equipment
- Audio Visual Equipment
- Industrial Equipment
- Other Switched-Mode Power Supply
Features include:
- 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
- Adjustable Standby Operating Point
- No Load Power Consumption < 15 mW
- Operation Mode
- Fixed Frequency, 100 kHz
- Green-Mode, 25 kHz to 100 kHz
- Burst Oscillation Mode
- Random Switching Function
- Slope Compensation Function
- Leading Edge Blanking Function
- Bias Assist Function
- Protections
- Overcurrent Protection (OCP): Pulse-by-Pulse
- Overload Protection with Timer (OLP): Auto-restart
- Overvoltage Protection (OVP): Auto-restart
- Thermal Shutdown (TSD): Auto-restart
