GNDA

PD

Ground for output stage (inductor to ground)

Monitor photodiode input. This input is connected to the monitor photodiode anode for

automatic power control.

26

CMPC Mean power control dominant pole capacitor

27

NC No connect and may be grounded for compatibility with MAX3869

28

TCSLOPE

Connecting a resistor between this pin and ground sets the temperature coefficient of

IMODSET (using the internal IC temperature).

29

MPCSET A resistor between this pin and ground sets the mean optical power

30

MODSET Modulation current set. Connect a resistor between this pin and ground to set.

31

OCASET Overcurrent alarm set. Connect a resistor between this pin and ground to set.
