Power IC for Quasi-Resonant Type Switching Power Supply with High Efficiency and Low Noise in Full Load Range
Sep. 2013
- General description
The STR- X6750B is power IC for quasi-resonant type switching power supply, incorporating a power MOSFET and a controller IC. The product achieves high efficiency and low noise power supply systems by the quasi-resonant operation.
- Features
- Quasi-resonant operation mode Achieves the optimal high efficiency and low noise power supply systems.
- Current mode control
- Built-in PWM oscillator
The PWM operates with the minimum frequency of around 22k Hz, until the quasi-resonant signal bees valid, reduces the stress on ponents at startup and load-shorted.
- Built-in soft start function
- Step-drive function, reducing switching noise
- Input pensation at overcurrent The function reduces the distortion of overcurrent operation point to AC input voltage change by adding three ponents.
- Avalanche energy...
