iT6801 Datasheet (inerhy) - SELF-OSCILLATING HALF-BRIDGE DRIVER

iT6801, SELF-OSCILLATING HALF-BRIDGE DRIVER

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.
