STR-X6750B datasheet


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.

Block Diagram :

STR-X6750B Pinout, Block Diagram


1. Quasi-resonant operation mode Achieves the optimal high efficiency and low noise
power supply systems.

2. Current mode control

3.  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.

4. Built-in soft start function

5. Step-drive function, reducing switching noise


1. Home appliances
2. OA equipments
3. Industry machines
4. Communication devices
