MAX1865
NAME
FUNCTION
Open-Drain Power-Good Output. POK is low when the output voltage is more than
1
1
POK
10% below the regulation point. POK is high impedance when the output is in
regulation. Connect a resistor between POK and VL for logic-level voltages.

COMP
OUT
Compensation Pin. Connect a series RC to GND to compensate the control loop.
Typical values are 47k Ω and 8.2nF.
Regulated Output Voltage High-Impedance Sense Input. Internally connected to a
resistive-divider and negative gain block (MAX1865).
Dual Mode Switching-Regulator Feedback Input. Connect to GND for the preset 3.3V

FB
output. Connect to a resistive-divider from output to FB to GND to adjust the output
voltage between 1.236V and 0.8 ? V IN . The feedback set point is 1.236V.
Open-Drain Output PNP Transistor Driver (Regulator #2). Internally connected to the
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

B5
drain of a P-channel MOSFET. B5 connects to the base of an external NPN pass
transistor to form a negative linear regulator.
Analog Gain-Block Feedback Input (Regulator #5). Connect to a resistive-divider
—
12
FB5
between the negative linear regulator’s output and a positive reference voltage,
typically one of the positive linear regulator outputs, to adjust the output voltage. The
feedback set point is at GND.
