Peak Inductor Current-Limit Setting
The parallel combination of current-sense resistors R10 and R11 (
Rsrc) sets the EV kit’s peak inductor current limit to 2A. Use the following equation to calculate the peak current limit:
where IILIM is the inductor peak current and RTOTAL is the total parallel resistance placed at the R10 and R11 (
Rsrc) PCB pads.
Refer to the Internal Switching MOSFET Current Limit section in MAX16812 IC data sheet
for additional information on setting the peak current-limit threshold.
Setting External LEDs Current
Resistors R13 and R14 (
Rcs) set the MAX16812 EV kit average LED current up to a maximum 360mA.
The potentiometer R2 allows the external LED current to be adjusted from 175mA (min) to 360mA (max).
The LED string current can be programmed using the following equation:
where ILED is the LED current, VREFI is the voltage at TP1, and 0.82Ω is the parallel resistance of R13 and R14 (
Rcs).
