LT1074/LT1076  
Step-Down Switching  
Regulator  
positive “buck” configuration but several design innova-  
tions allow this device to be used as a positive-to-negative  
converter, a negative boost converter, and as a flyback  
converter. The switch output is specified to swing 40V  
below ground, allowing the LT1074 to drive a tapped-  
inductor in the buck mode with output currents up to 10A.  
FEATURES  
■
5A Onboard Switch (LT1074)  
■
100kHz Switching Frequency  
■
Greatly Improved Dynamic Behavior  
■
Available in Low Cost 5 and 7-Lead Packages  
■
Only 8.5mA Quiescent Current  
The LT1074 uses a true analog multiplier in the feedback  
loop. This makes the device respond nearly instanta-  
neously to input voltage fluctuations and makes loop gain  
independent of input voltage. As a result, dynamic behav-  
ior of the regulator is significantly improved over previous  
designs.  
■
Programmable Current Limit  
■
Operates Up to 60V Input  
■
Micropower Shutdown Mode  
U
APPLICATIO S  
On-chip pulse by pulse current limiting makes the LT1074  
nearlybust-proofforoutputoverloadsorshorts.Theinput  
voltage range as a buck converter is 8V to 60V, but a self-  
boot feature allows input voltages as low as 5V in the  
inverting and boost configurations.  
■
Buck Converter with Output Voltage Range of 2.5V  
to 50V  
■
Tapped-Inductor Buck Converter with 10A Output  
at 5V  
■
Positive-to-Negative Converter  
■
Negative Boost Converter  
The LT1074 is available in low cost TO-220 or TO-3  
packages with frequency pre-set at 100kHz and current  
limit at 6.5A (LT1076 = 2.6A). A 7-pin TO-220 package is  
also available which allows current limit to be adjusted  
down to zero. In addition, full micropower shutdown can  
be programmed. See Application Note 44 for design  
details.  
■
Multiple Output Buck Converter  
U
DESCRIPTIO  
The LT®1074 is a 5A (LT1076 is rated at 2A) monolithic  
bipolar switching regulator which requires only a few  
external parts for normal operation. The power switch, all  
oscillator and control circuitry, and all current limit com-  
ponents,areincludedonthechip.Thetopologyisaclassic  
A fixed 5V output, 2A version is also available. See LT1076-5.
