The LTC® 1265 is a monolithic step-down current modeDC/DC converter featuring Burst ModeTMoperation at low output current. The LTC1265 incorporates a 0.3W switch(VIN =10V) allowing up to 1.2A of output current.
Under no load condition, the converter draws only 160m A.In shutdown it typically draws a mere 5m A 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. TheLTC1265 incorporates automatic power saving Burst Modeoperation to reduce gate charge losses when the loadcurrents drop below the level required for continuousoperation.
The inductor current of LTC1265 is user-programmable via an externalcurrent sense resistor. Operation up to 700kHz permitsthe use of small surface mount inductors and capacitors.
