LT1072  
1.25A High Efficiency  
Switching Regulator  
U
FEATURES  
DESCRIPTIO  
The LT®1072 is a monolithic high power switching  
regulator. It can be operated in all standard switching  
configurations including buck, boost, flyback, forward,  
inverting and “Cuk”. A high current, high efficiency switch  
is included on the die along with all oscillator, control, and  
protection circuitry. Integration of all functions allows the  
LT1072 to be built in a standard 5-pin TO-3 or TO-220  
power package as well as the 8-pin miniDlP. This makes it  
extremelyeasytouseandprovides“bustproof”operation  
similar to that obtained with 3-pin linear regulators.

Internal 1.25A Switch  
■
Very Few External Parts Required  
■
Self-Protected Against Overloads  
■
Operates in Nearly All Switching Topologies  
■
Shutdown Mode Draws Only 50µA Supply Current  
■
Flyback-Regulated Mode has Fully Floating Outputs  
■
Can be Externally Synchronized  
U
TheLT1072operateswithsupplyvoltagesfrom3Vto60V,  
and draws only 6mA quiescent current. It can deliver load  
power up to 20 watts with no external power devices. By  
utilizing current-mode switching techniques, it provides  
excellent AC and DC load and line regulation.  
APPLICATIO S  
■
Logic Supply 5V at 2.5A  
5V Logic to ±15V Op Amp Supply  
■
■
Offline Converter up to 50W  
Battery Upconverter  
■
The LT1072 has many unique features not found even on  
the vastly more difficult to use low power control chips  
presently available. It uses an adaptive anti-sat switch  
drive to allow very wide ranging load currents with no loss  
in efficiency. An externally activated shutdown mode  
reduces total supply current to 50µA typical for standby  
operation. Totally isolated and regulated outputs can be  
generatedbyusingtheoptional“flybackregulationmode”  
builtintotheLT1072, withouttheneedforoptocouplersor  
extra transformer windings.

USER NOTE:  
This data sheet is only intended to provide specifications, graphs, and a general functional  
description of the LT1072. Application circuits are included to show the capability of the LT1072.  
A complete design manual (AN-19) should be obtained to assist in developing new designs. This  
manualcontainsacomprehensivediscussionofboththeLT1070andtheexternalcomponentsused  
with it, as well as complete formulas for calculating the values of these components. The manual  
can also be used for the LT1072 by factoring in the lower switch current rating.
