DescriptionThe LT1173CS8 is a versatile micropower DC/DC converter.The device requires only four external components to deliver a fixed output of 5V or 12V. Supply voltage ranges from 2.0V to 12V in step-up mode and to 30V in step-down mode.The LT1173CS8 functions equally well in step-up, stepdown,or inverting applications.
Features of the LT1173CS8 are:(1)operates at supply voltages from 2.0V to 30V;(2)consumes only 110mA supply current;(3)works in step-up or step-down mode;(4)only three external components required;(5)low battery detector comparator on-chip;(6)user-adjustable current limit;(7)internal 1A power switch;(8)fixed or adjustable output voltage versions;(9)space saving 8-Pin miniDIP or SO8 package.Applications of the LT1173CS8 are:(1)flash memory Vpp generators;(2)3V to 5V,5V to 12V converters;(3)9V to 5V, 12V to 5V converters;(4)LCD bias generators;(5)peripherals and add-on cards;(6)battery backup supplies;(7)laptop and palmtop computers;(8)cellular telephones;(9)portable instruments.
The absolute maximum ratings of the LT1173CS8 can be summarized as:(1):the symbol is VIN,the parameter is supply voltage,the rating is 36,the unit is V;(2):the symbol is PD,the parameter is maximum power dissipation,the rating is 500,the unit is mW;(3):the symbol is VSW1,the parameter is SW1 pin voltage,the rating is 50,the unit is V;(4):the symbol is VSW2,the parameter is SW2 pin voltage,the rating is -0.5 to VIN,the unit is V;(5):the parameter is feedback pin voltage,the rating is 5,the unit is V;(6):the parameter is sense pin voltage,the rating is 36,the unit is V;(7):the parameter is maximum switch current,the rating is 1.5,the unit is A;(8):the parameter is operating temperature range,the rating is 0 to 70,the unit is ;(9):the parameter is storage temperature range,the rating is -65 to 150,the unit is ;(10):the parameter is lead temperature(soldering,10 sec),the rating is 300,the unit is .
