STR-W6734 Overview
The STR-W6734 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 and the bottom-skip quasi-resonant operation.
STR-W6734 Key Features
- Multi operation mode The operation mode switching according to load conditions achieves the optimal high efficiency and
- Current mode control
