LT1372/LT1377  
500kHz and 1MHz  
High Efficiency  
1.5A Switching Regulators

DESCRIPTION  
FEATURES  
The LT®1372/LT1377 are monolithic high frequency  
switching regulators. They can be operated in all standard  
switching configurations including boost, buck, flyback,  
forward,invertingand“Cuk.”A1.5Ahighefficiencyswitch  
is included on the die, along with all oscillator, control and  
protection circuitry. All functions of the LT1372/LT1377  
are integrated into 8-pin SO/PDIP packages.  
■
Faster Switching with Increased Efficiency  
■
Uses Small Inductors: 4.7µH  
■
All Surface Mount Components  
■
Only 0.5 Square Inch of Board Space  
■
Low Minimum Supply Voltage: 2.7V  
■
Quiescent Current: 4mA Typ  
■
Current Limited Power Switch: 1.5A  
■
Regulates Positive or Negative Outputs  
The LT1372/LT1377 typically consumes only 4mA quies-  
centcurrent and has higher efficiencythan previous parts.  
High frequency switching allows for very small inductors  
to be used. All surface mount components consume less  
than 0.5 square inch of board space.  
■
Shutdown Supply Current: 12µA Typ  
■
Easy External Synchronization  
■
8-Pin SO or PDIP Packages  
U
APPLICATIONS  
New design techniques increase flexibility and maintain  
ease of use. Switching is easily synchronized to an exter-  
nal logic level source. A logic low on the shutdown pin  
reduces supply current to 12µA. Unique error amplifier  
circuitry can regulate positive or negative output voltage  
while maintaining simple frequency compensation tech-  
niques. Nonlinear error amplifier transconductance re-  
duces output overshoot on start-up or overload recovery.  
Oscillator frequency shifting protects external compo-  
nents during overload conditions.
