PT6360 Series
11 A 12-V Input Adjustable
Integrated Switching Regulator
SLTS179A - JANUARY 2003 - REVISED APRIL 2003
Pin Descriptions
Vin: The positive supply voltage input for the module
with respect to the common GND.
Vout: This is the regulated output voltage from the mod-
ule with respect to the common GND.
GND: The common node to which the input, output, and
external control signals are referenced.
Inhibit*: This is an open-collector (open-drain) negative
logic input, that is referenced to GND. Driving this pin to
GND disables the module’s output voltage. If Inhibit* is
left open-circuit, the output will be active whenever a
valid input source is applied.
V_o Adjust: This pin is used to trim the output voltage to a
value within the range of approximately ±15 % of nominal.
The adjustment method uses an external resistor. The
resistor is connected from V_o Adjust to either the GND
or (+)Sense, in order to adjust the output either up or
down, respectively.
(+)Sense: An external remote sense input is provided to
allow the regulation circuit to compensate for voltage
drop between the module and the load. For optimal
voltage accuracy (+)Sense should be connected to V_out. If
desired, (+)Sense may also be left open circuit.
