BL8080 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 components and system level cost.
Compared 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
