特点 High Efficiency: Up to 95% Current Mode Operation for Excellent Line and Load Transient Response Internal 0.3 Ohms Power Switch (V IN = 10V) Short-Circuit ProtectionLow Dropout Operation: 100% Duty CycleLow-Battery DetectorLow 160μA Standby Current at Light Loads Active-High Micropower Shutdown: I Q < 15μA Peak Inductor Current Independent of Inductor ValueAvailable in 14-pin SO Package典型应用典型应用描述描述 The LTC?1265 is a monolithic step-down current mode DC/DC converter featuring Burst Mode ? operation at low output current. The LTC1265 incorporates a 0.3 Ohms switch (V IN =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.
