FUNCTION
Compensation Pin for Error Amplifier. Connect a series RC from COMP to ground. Typical values
are 47k and 580pF.
Feedback. The FB regulation voltage is 1.24V nominal. Connect an external resistor-divider center
tap here and minimize the trace area. Set V OUT according to the Output Voltage Selection section.
IC Supply. There is an internal switch between IN and V L and the switch disconnects when an
overvoltage condition on IN is detected. Bypass V L to GND with a 1 μF capacitor.
Ground
Switch. LX is the drain of the internal MOSFET.
Supply Voltage Input. Bypass IN with a minimum 1 μF ceramic capacitor directly to GND.
Shutdown Control Input. Drive SHDN high to turn on the MAX17112 for normal operation. Connect a
capacitor to the SHDN pin to create a delayed turn-on. The time delay is 0.25 x C (typ), C in
microfarads. SHDN can be driven from a logic signal directly, in which case a resistor is required
in series with SHDN .
Soft-Start Control. Connect a soft-start capacitor (C SS ). Leave open for no soft-start. The soft-start
capacitor is charged at a rate of 4 μA/C SS .
Exposed Pad. Connect to GND.
