LT1370

500kHz High Efficiency

6A Switching Regulator

FEATURES

DESCRIPTION

The LT

1370 is a monolithic high frequency current mode

switching regulator. It can be operated in all standard

switching configurations including boost, buck, flyback,

forward, inverting and “Cuk.” A 6A high efficiency switch

is included on the die, along with all oscillator, control and

protection circuitry.

The LT1370 typically consumes only 4.5mA quiescent

current and has higher efficiency than previous parts.

High frequency switching allows for very small inductors

to be used.

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

reduces output overshoot on start-up or overload recov-

ery. Oscillator frequency shifting protects external com-

ponents during overload conditions.
