LTC1574  
LTC1574-3.3/LTC1574-5  
High Efficiency Step-Down  
DC/DC Converters  
with Internal Schottky Diode  
U
FEATURES  
DESCRIPTIO  
The LTC®1574 is a family of easy-to-use current mode  
DC/DC converters ideally suited for 9V to 5V, 5V to 3.3V  
and inverting operation. With an internal 0.9Ω switch (at  
a supply voltage of 12V) and a low forward drop Schottky  
diode (0.450V typ at 200mA, TA = 25°C), the LTC1574  
requires only three external components to construct a  
complete high efficiency DC/DC converter.  
■
High Efficiency: Up to 94%  
■
Usable in Noise-Sensitive Products  
■
Peak Inductor Current Independent of Inductor Value  
■
Short-Circuit Protection  
■
Internal Low Forward Drop Schottky Diode  
■
Only Three External Components Required  
■
Wide VIN Range: 4V to 18.5V (Absolute Maximum)  
■
Low Dropout Operation  
Low-Battery Detector  
Pin Selectable Current Limit  
Under no load condition, the LTC1574 draws only 130µA.  
In shutdown, it draws a mere 2µA making this converter  
ideal for battery-powered 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.  
■
■
■
Internal 0.9Ω Power Switch: VIN < 11V  
■
Standby Current: 130µA  
■
Active Low Micropower Shutdown  
U
The maximum inductor current of the LTC1574 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.
