Features
„ Internal Clock Using RCT
„ External Sync Function Using RCT
„ Dead Time Control Using Resistor
„ Shut Down (Disable Mode)
„ Internal Shunt Regulator
„ UVLO Function, High and Low Side
Description
The FAN7387 is a simple control IC for common half-
bridge inverters, SMPS, and ballast for fluorescent and
HID lamps. The FAN7387 has an oscillating circuit using
an external resistor and capacitor. The frequency
variation is very stable across a wide temperature range.
The FAN7387 has a external pin for dead time control
and shutdown. Using this resistor, the designer can
choose the optimum dead time to reduce power loss on
switching devices, such as transistors and MOSFETs.
Applications
„ Half-Bridge Inverter
„ SMPS
„ Ballast Solution for High-Intensity Discharge
(HID) Lamp
„ Ballast for Fluorescent Lamp
