DESCRIPTIO  
EATURE

F
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  
components to construct a complete high efficiency  
DC/DC converter.

Short-Circuit Protection  
Optimized for 5V to –5V Applications  
Wide VIN Range: 4V to 18.5V  
Low Dropout Operation  
Under a no load condition the LT1174 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 continu-  
ously allowing the user to maximize the life of the battery  
source.  
Low-Battery Detector  
Pin Selectable Current Limit  
Internal 0.9Ω Power Switch: VIN = 9V  
Only Four External Components Required  
130µA Standby Current  
Active Low Micropower Shutdown  
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.
