Description
The STR-W6734 is power IC for quasi-resonant type switching power supply, incorporating a power MOSFET and a controller IC.
Package
Package name: TO-220F-6L (FM207)
Sep.2013
Features
- Multi operation mode The operation mode switching according to load conditions achieves the optimal high efficiency and low noise power supply systems across the full load range.
- Current mode control.
- Built-in PWM oscillator
The PWM operates with the minimum frequency of around 22kHz, until the quasi-resonant signal becomes valid, reduces the stress on components at startup and load-shorted.
- Built-in soft start function.
- Step-drive function, reducing switching noise.
