Description
Current sense feedback.
Compensation for the current sense feedback.
Soft start in two steps. Two-interval current sources of 50µA and 0.6µA
provide 1:26.6 ratio between the two time intervals of soft start. Connect a
capacitor between this pin and the ground to adjust the soft-start timing.
The output of the brightness D/A converter. The brightness has 32 adjust-
able levels. The default range is between 0.9V to 2.5V.
The output of the contrast D/A converter. The contrast has 256 levels from
0.8V to 2.8 V (8mV per step). This output has a current capability of up to
2mA.
Timing resistor.
Timing capacitor. CT and RT set the clock frequency. Fs = 1.60 / (RT * CT).
Ground.
Gate drive output for the N-MOSFET.
Gate drive output for the P-MOSFET.
Over-voltage protection sense input.
