PT6460 Series  
14-A 5-V Input Adjustable  
Integrated Switching Regulator  
SLTS178B - JANUARY 2003 - REVISED JUNE 2003  
Pin Descriptions  
VIN: The positive supply voltage input for the module  
with respect to the common GND.  
Vo Adjust: This pin is used to trim the output voltage  
over a typical range of 15 % of nominal. The adjust-  
ment method uses an external resistor. The resistor is  
connected from Vo Adjust to either the GND or (+)Sense,  
in order to adjust the output either up or down, respec-  
tively. Consult the related application note for the adjust  
limits on a specific part.  
V
OUT: 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. Pulling this pin  
low disables the modules output voltage. If Inhibit* is  
left open-circuit, the output will be active whenever a  
valid input source is applied.  
Vsense: 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 Vsense should be connected to VOUT. If  
desired, Vsense may also be left open circuit.
