LTC1174

LTC1174-3.3/LTC1174-5

High Efficiency

Step-Down and Inverting

DC/DC Converter

FEATURES

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

components to construct a complete high efficiency

DC/DC converter.

■

High Efficiency: Up to 94%

■

Peak Inductor Current Independent of

Inductor Value

Short-Circuit Protection

■

Optimized for 5V to –5V Applications

■

Wide V_INRange: 4V to 18.5V

■

Low Dropout Operation

UnderanoloadconditiontheLTC1174drawsonly130µA.

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.

Pin Selectable Current Limit

■

Internal 0.9Ω Power Switch: V_IN= 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.
