NAME
FUNCTION
1
1
POK
Open-Drain Power-Good Output. POK is low when any output voltage is more than
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.
2
2
COMP
Compensation Pin. Connect the compensation network to GND to compensate the
control loop.
3
3
OUT
Regulated Output Voltage High-Impedance Sense Input. Internally connected to a
resistive-divider and negative gain block (MAX1965).
4
4
FB
Dual-Mode Switching-Regulator Feedback Input. Connect to GND for the preset 3.3V
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.

B2
Open-Drain Output PNP Transistor Driver (Regulator 2). Internally connected to the
drain of a DMOS. B2 connects to the base of an external PNP pass transistor to form a
positive linear regulator.
6
6
FB2
Analog Gain Block Feedback Input (Regulator 2). Connect to a resistive-divider
between the positive linear regulator
’
s output and GND to adjust the output voltage.
The feedback set point is 1.24V.
