LT1170/LT1171/LT1172  
100kHz, 5A, 2.5A and 1.25A  
High Efficiency Switching Regulators  
FeaTures  
DescripTion  
The LT®1170/LT1171/LT1172 are monolithic high power-  
switching regulators. They can be operated in all standard  
switching configurations including buck, boost, flyback,  
forward,invertingand“Cuk.”Ahighcurrent,highefficiency

5-pin TO-3 or TO-220 power package as well as the 8-pin  
packages (LT1172). This makes them extremely easy to  
use and provides “bust proof” operation similar to that  
obtained with 3-pin linear regulators.

Surface Mount Packages  
The LT1170/LT1171/LT1172 operate with supply voltages  
from 3V to 60V, and draw only 6mA quiescent current.  
They can deliver load power up to 100W with no exter-  
nal power devices. By utilizing current-mode switching  
techniques, they provide excellent AC and DC load and  
line regulation.

USER NOTE:  
This data sheet is only intended to provide specifications, graphs, and a general functional  
description of the LT1170/LT1171/LT1172. Application circuits are included to show the capability  
of the LT1170/LT1171/LT1172. A complete design manual (AN19) should be obtained to assist in  
developing new designs. This manual contains a comprehensive discussion of both the LT1070  
and the external components used with it, as well as complete formulas for calculating the values  
of these components. The manual can also be used for the LT1170/LT1171/LT1172 by factoring in  
the higher frequency. A CAD design program called SwitcherCAD is also available.
