Description
The FAN7314A provides all the control functions for a
series parallel resonant converter as well as a pulse
width modulation (PWM) controller to develop a supply
voltage. Typical operating frequency range is between
30kHz and 250kHz, depending on the CCFL and the
transformer's characteristics.
The FAN7314A is available in a 20-SOIC package.
