Overview
iT6801 SELF-OSCILLATING HALF-BRIDGE DRIVER 1.
Description iT6801 is a half-bridge driver with programmable oscillator within a SOP-8L package to drive both lower MOSFET and floating upper MOSFET.
It is suitable for electronic ballast of fluorescent lamp.
It is equipped with internal clamp of 17.
2 V zener diode, so the VCC voltage is easily regulated.
For proper operation assurance and low power startup, it is designed with internal under voltage lockout (UVLO), so it takes little current for supply capacitor voltage to builds up.
Oscillator frequency is controlled by the current drawn out from RT, which acts as minimum base frequency.
The same current is duplicated internally to double base ...
