DescriptionThe LTC1174HVCN8 is a simple current mode DC/DC converter ideally suited for 9V to 5V, 5V to 3.3V, or 5V to 5V operation. With an internal 0.9 switch (at a supply voltage of 9V), the LTC1174HVCN8 requires only four external components to construct a complete high efficiency DC/DC converter.
Features of the LTC1174HVCN8 are:(1)high efficiency: up to 94%;(2)peak inductor current independent of inductor value;(3)short-circuit protection;(4)optimized for 5V to 5V applications;(5)wide VIN range: 4V to 18.5V;(6)low dropout operation;(7)low-battery detector;(8)pin selectable current limit;(9)internal 0.9 power switch: VIN = 9V;(10)only four external components required;(11)130mA standby current;(12)active low micropower shutdown.Applications of the LTC1174HVCN8 are:(1)distributed power systems;(2)step-down converters;(3)inverting converters;(4)memory backup supply;(5)portable instruments;(6)battery-powered equipment.
The absolute maximum ratings of the LTC1174HVCN8 can be summarized as:(1):the parameter is input supply voltage,the rating is -0.3 to 18.5,the unit is V;(2):the parameter is switch current,the rating is 1,the unit is A;(3):the parameter is switch voltage,the rating is VIN18.5,the unit is V;(4):the parameter is operating temperature range,the rating is 0 to 70,the unit is ; (5):the parameter is extended commercial temperature range,the rating is -40 to 85,the unit is ;(6):the parameter is junction temperature range,the rating is 125,the unit is ;(7):the parameter is storage temperature range,the rating is -65 to 150,the unit is ;(8):the parameter is lead temperature (soldering,10 sec),the rating is 300,the unit is .
