Product Summary
The STR-X6768 is a Power IC. The STR-X6768 is power IC for quasi-resonant type switching power supplies, 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. The applications of the STR-X6768 include Digital Consumer Equipment; LCD-TVs, PDP-TVs, CRT-TVs, etc., Home Appliances, OA Equipments, Industry Machines, Communication Devices, Others.
Features
STR-X6768 features: (1)Current-Mode Control; (2)Built-in PWM Oscillator The PWM operates with the minimum frequency of around 22 kHz, until the quasi-resonant signal becomes valid, reduces the stress on components at startup and load-shorted; (3)Soft-Start Function; (4)Step-Drive Function, reducing switching noise; (5)Built-in Maximum ON Time Limitation Circuit The function limits the maximum ON time of power MOSFET, during the transitions at low input voltage, power ON/OFF; (6)Input Compensation at Over current The function reduces the distortion of over current operation point to AC input voltage change by adding three components; (7)Built-in Avalanche Energy Guaranteed High-Voltage Power MOSFET.
