Description
The FAN7547A provides all control functions for a
current-fed, push-pull, self-oscillation type converter and
also contains a pulse-width-modulated (PWM) controller
to develop a supply voltage. Typical operating frequency
range is from 30kHz to 100kHz, depending on the cold
cathode fluorescent lamp (CCFL) and the transformer's
characteristics.
