BL8080
BL8080 is HIGH INTEGRATED PWM CONTROLLER manufactured by BELLING.
GENERAL DISCRIPTION
The BL8080 is a PWM controller designed to drive high voltage NPN transistors. It integrates an oscillator, cycle-by-cycle current limit, thermal protection and over voltage protection, great reducing the number of external ponents and system level cost. pared to conventional controller, BL8080 has a significantly smaller startup current of less than 20uA, which allows large startup resistor that enabes further power saving. The frequency can be adjusted from an external capcitor. At light load condition the frequency of BL8080 can be varied according to the load, which improves the light load efficiency.
