LT1374
4.5A, 500kHz Step-Down
Switching Regulator
U FEATURES DESCRIPTIO ■ The LT ®1374 is a 500kHz monolithic buck mode switching
regulator. A 4.5A switch is included on the die along with
all the necessary oscillator, control and logic circuitry. High
switching frequency allows a considerable reduction in the
size of external components. The topology is current mode
for fast transient response and good loop stability. Both
fixed output voltage and adjustable parts are available. ■
