FAN7300 - LCD Back Light Inverter Drive IC

Description

The FAN7300 provides all the control functions for a series parallel resonant converter and also contains a pulse width modulation (PWM) controller to develop a supply voltage.

Typical operating frequency range is between 30kHz and 100kHz depending on the CCFL and the transformer's characteristics.

Features

  • High Efficiency Single Stage Power Conversion Wide Input Voltage Range 6V to 25V Back Light Lamp Ballast and Soft Dimming Few External Components Precision Voltage Reference Trimmed to 2% Soft Start PWM and PFM Control Analog, Burst and Mixed Dimming Function Allows All N-Channel MOSFET Drive Double Pulse Suppression Logic Open Lamp Detection Output Short Ci.
