ON/OFF Control Input. ON is used to implement the undervoltage lockout threshold and resets the part
after a fault condition for the latched-off version (MAX5933A/MAX5933C/MAX5947A, see the Detailed
Description section).
Power-Good Comparator Input. Connect a resistive divider from output to FB to GND to monitor the output
voltage (see the Power-Good Detection section). FB is also used as a feedback for the current-limit
foldback function.
Open-Drain Power-Good Output. PWRGD is high (PWRGD is low) when V
is low (PWRGD is high) when V
Ground
Timing Input. Connect a capacitor from TIMER to GND to program the maximum time the part is allowed to
remain in current limit (see the TIMER section).

Current-Sense Input. Connect a sense resistor from V
MOSFET.
Power-Supply Input. Bypass V
