FAN7387 — Self-Oscillated, High-Voltage Gate Driver March 2014 FAN7387 Self-Oscillated, High-Voltage Gate Driver 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 halfbridge 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 an 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 8-DIP 8-SOP Ordering Information Part Number FAN7387MX Note: 1.
