DescriptionThe LTC1265CS-3.3 is one member of the LTC1265 family which is designed as the 1.2A, high efficiency step-down DC/DC converter that can be used in (1)5V to 3.3V conversion; (2)distributed power systems; (3)step-down converters; (4)inverting converters; (5)memory backup supply; (6)portable instruments; (7)battery-powered equipment; (8)cellular telephones. Also this device incorporates automatic power saving Burst Mode operation to reduce gate charge losses when the load currents drop below the level required for continuous operation.
Features of the LTC1265CS-3.3 are:(1)high efficiency: up to 95%; (2)current mode operation for excellent line and load transient response; (3)internal 0.3W power switch (VIN = 10V); (4)short-circuit protection; (5)low dropout operation: 100% duty cycle; (6)low-battery detector; (7)low 160mA standby current at light loads; (8)active-high micropower shutdown: IQ < 15mA; (9)peak inductor current independent of inductor value; (10)available in 14-pin SO package.
The absolute maximum ratings of the LTC1265CS-3.3 can be summarized as:(1)input supply voltage (pins 1, 2, 13):-0.3V to 13V;(2)DC switch current:1.2 A;(3)peak switch current:1.6 A;(4)switch voltage:VIN-13.0;(5)operating temperature range:0° to 70°C;(6)junction temperature:125°C;(7)storage tempera-ture range:-65° to 150°C;(8)lead temperature (soldering, 10 sec):300°C.
