operation at low
output current. The LTC1265 incorporates a 0.3鈩?switch
(V
IN
=10V) allowing up to 1.2A of output current.
Under no load condition, the converter draws only 160碌A(chǔ).
In shutdown it typically draws a mere 5碌A(chǔ) making this
converter ideal for current sensitive applications. In drop-
out the internal P-channel MOSFET switch is turned on
continuously maximizing the life of the battery source. The
LTC1265 incorporates automatic power saving Burst Mode
operation to reduce gate charge losses when the load
currents drop below the level required for continuous
operation.
The inductor current is user-programmable via an external
current sense resistor. Operation up to 700kHz permits
the use of small surface mount inductors and capacitors.
