NAME
FUNCTION
Open-Drain Power-Good Output. POK is low when any output voltage is more than
1
1
POK
10% below its regulation point. POK is high impedance when all the outputs are in
regulation. Connect a resistor between POK and VL for logic-level voltages.

COMP
OUT
Compensation Pin. Connect the compensation network to GND to compensate the
control loop.
Regulated Output Voltage High-Impedance Sense Input. Internally connected to a
resistive-divider and negative gain block (MAX1965).
Dual-Mode Switching-Regulator Feedback Input. Connect to GND for the preset 3.3V
4
4
FB
output. Connect to a resistive-divider from the output to FB to GND to adjust the output
voltage between 1.236V and 0.75 ? V IN . The feedback set point is 1.236V.
Open-Drain Output PNP Transistor Driver (Regulator 2). Internally connected to the
5
5
B2
drain of a DMOS. B2 connects to the base of an external PNP pass transistor to form a
positive linear regulator.
Analog Gain Block Feedback Input (Regulator 2). Connect to a resistive-divider
6
6
FB2
between the positive linear regulator ’ s output and GND to adjust the output voltage.
The feedback set point is 1.24V.
