Description
General part information
LTC1265 Series
The LTC1265 is a monolithic step-down current mode DC/DC converter featuring Burst Mode™ operation at low output current. The LTC1265 incorporates a 0.3Ω switch (VIN=10V) allowing up to 1.2A of output current.Under no load condition, the converter draws only 160µA. In shutdown it typically draws a mere 5µA making this converter ideal for current sensitive applications. In dropout 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.Applications5V to 3.3V ConversionDistributed Power SystemsStep-Down ConvertersInverting ConvertersMemory Backup SupplyPortable InstrumentsBattery-Powered EquipmentCellular Telephones
