LTC1174HVCS8-5#PBF

LTC®1174 is a simple current mode high efficiency step-down and inverting DC/DC converter. Under a no load condition this draws only 130µA. In shutdown, it draws a mere 1µA making this converter ideal for current sensitive applications. In dropout, the internal P-channel MOSFET switch is turned on continuously allowing the user to maximize the life of the battery source. Operation up to 200KHz permits the use of small surface mount inductors and capacitors. Typical applications are distributed power systems, step-down converters, inverting converters, memory backup supply, portable instruments, battery-powered equipment.

• High efficiency is up to 94%, peak inductor current independent of inductor value
• Short-circuit protection, low dropout operation
• Low-battery detector, pin selectable current limit
• Only four external components required, active low micropower shutdown
• Feedback voltage range from 1.2 to 1.3V (TA=25°C. VIN=9V, V active-low SHUTDOWN=VIN, IPGM=0V)
• Feedback current is 1µA
• Regulated output voltage range from 3.14 to 3.46V (TA=25°C. VIN=9V, V active-low SHUTDOWN=VIN)
• 8-lead plastic SO package
• Operating temperature range from 0°C to 70°C
