STR6A169HVD
STR6A169HVD is Off-Line PWM Controller manufactured by Sanken.
- Part of the STR6A153MV comparator family.
- Part of the STR6A153MV comparator family.
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
- Soft Start Function
- Adjustable Standby Operating Point
No Load Power Consumption < 15 m W
- Operation Mode
Fixed Frequency: 65 k Hz / 100 k Hz Green-Mode: 25 k Hz to 65 k Hz / 25 k Hz to 100 k Hz Burst Oscillation Mode
- Random Switching Function
- Slope pensation Function
- Leading Edge Blanking Function
- Bias Assist Function
- Protections
- Two Types of Overcurrent Protection (OCP): Pulseby-Pulse, built-in pensation circuit to minimize OCP point variation on AC input voltage Overload Protection with Timer (OLP): Auto-restart Overvoltage Protection (OVP): Latched shutdown or auto-restart Thermal Shutdown (TSD): Latched shutdown or autorestart-
- With hysteresis
