FA N 7318APin DefinitionsPin #NameDescription— LC 1 TIMER This pin is for protection delay time setting. Error amplifier output. Typically, a compensation capacitor is connected to this pin from the 2 CMP ground. D B 3 ADIM This pin is the input for negative analog dimming. a This pin is for programming the switching frequency. Typically, a capacitor is connected to cklight 4 CT this pin from ground and a resistor is connected to this pin from the REF pin. This pin is 5V reference output. Typically, resistors are connected to this pin from the CT pin 5 REF and the BCT pin. Invert This pin is for programming the frequency of the burst dimming. Typically, a capacitor is 6 BCT connected to this pin from ground and a resistor is connected to this pin from the REF pin. This pin is the input for negative burst dimming. The voltage range of 0.5 to 2V at this pin e 7 BDIM r D controls burst mode duty cycle from 0% to 100%. r 8 ENA This pin is for turning on/off the IC. ive IC 9 GND This pin is the ground. 10 OUTB This pin is NMOS gate-drive output.
