FUNCTION
Lamp Oscillator Resistor Adjust. A resistor (R LOSC ) to ground on this pin sets the frequency of
the lamp oscillator (f LFS:OSC ). [R LOSC x f LFS:OSC = 1.6E9].
Burst Dimming DPWM Oscillator Resistor Adjust. A resistor (RPOSC) to ground on this lead

sets the frequency (f DSR:OSC ) of the burst-dimming DPWM oscillator. [R POSC x f DSR:OSC = 4.0E6
for DS3992Z-09P and DS3992Z-09N and R POSC x f DSR:OSC = 8.0E6 for DS3992Z-18P and
DS3992Z-18N].

Lamp Brightness Control. An analog voltage at this input controls the lamp brightness. See
Table 1 for details.
Supply Voltage Monitor. The DC inverter supply voltage is monitored by an external resistor

divider. The resistor-divider should be set such that it provides 2V at this pin for the minimum
allowable range of the DC inverter supply. Pulling this input below 2V will turn the lamps off and
reset the controller. Connect to V CC if not used.
