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

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.
