Programming
The 6-PAK™ is programmed through the Control SIP. All
connected Power Boosters follow the Control SIP
programming. To program the 6-PAK™ for V
out
<3.3, connect
a resistor across the TRIM and V
o
pins. For V
out
>3.3, resistor
is connected across TRIM and GND.

Ambient Temp. (Deg. C)
NOTE: The ambient temperature is as measured at approx. 1/4” away on the back side of the unit, with the probe end at approx. center
(vertical & horizontal). For thermal performance, the unit was mounted on a 4”x4” PCB (with ground plane) & enclosed in a box so that it
operates in a controlled environment.
