High Efficiency Step-Down and Inverting
DC/DC Converter
DESCRIPTIO
The LTC®1174 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 0.9Ω switch (at a supply voltage of 9V), the LTC1174 requires only four external ponents to construct a plete 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...
