STR6A163HZ
Description
The STR6A100HZ series are power ICs for switching power supplies, incorporating a 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
- 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
- Brown-in and Brown-out Function
- No Load Power Consumption, PIN < 25m W
- Automatically changed operation mode in response to load conditions
- Fixed switching frequency mode, 100 k Hz (typ.) in normal operation.
- Green mode, 25 k Hz (typ.) to 100 k Hz (typ.) in middle to light load.
- Burst oscillation mode in light load.
- Random Switching Function
- Slope pensation Function
- Leading Edge Blanking Function
