Programmable Switch-Mode LED Driver
with Analog-Controlled PWM Dimming
Digital Soft-Start Duration Register (SS)
The MAX16816 programmable soft-start feature allows
the load current to ramp up in a controlled manner, elimi-

5.5V (min) rising threshold voltage. Adjust the soft-start
duration by configuring the EEPROM. Enter ‘111’ to dis-
able the soft-start feature. See Table 6.
Oscillator Enable/Disable Register (RTOF)
The MAX16816 features a programmable accurate
RTSYNC oscillator and resistor synchronized to an
external clock. Set the EEPROM bit RTOF to ‘1’ to dis-
able the external sync mode, and the RTSYNC oscilla-
tor, and to use the fixed internal frequency of 125kHz
as the switching frequency. Set RTOF to ‘0’ to synchro-
nize with an external oscillator or to program the exter-
nal oscillator frequency with an external resistor, R T .
See Table 7.
Slope Compensation Register (ESLP)
The MAX16816 uses an internally generated ramp to
stabilize the current loop when operating at duty cycles
above 50%. Set the compensating slope by adjusting
the peak ramp voltage through the on-chip EEPROM.
See Tables 8 and 9.
