Product Overview

The LTC1174CS8-3.3#PBF is a simple current mode DC/DC Converter with an internal 0.9R switch (at a supply voltage of 9V), the LTC1174 requires only four external components to construct a complete high efficiency DC/DC converter. Under a no load condition the LTC1174 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. The maximum inductor current of the LTC1174 family is pin selectable to either 340mA or 600mA, optimizing efficiency for a wide range of applications. Operation up to 200kHz permits the use of small surface mount inductors and capacitors. For applications requiring higher output current or ultrahigh efficiency.
  • 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
  • 130µA Standby current
