自振荡，高压栅极驱动器 Self-Oscillated, High-Voltage Gate Driver
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.
