FEATURES
DESCRIPTION
The LTM®8051 is quad 40VIN, 1.2A step-down Silent
Switcher μModule® regulator. The Silent Switcher archi-
tecture minimizes EMI while delivering high efficiency at
frequencies up to 3MHz. Included in the package are the
controllers, power switches, inductors, and support com-
ponents. Operating over a wide input voltage range, the
LTM8051 supports output voltages from 0.8V to 8V, and
a switching frequency range of 300kHz to 3MHz, each set
by a single resistor. Only the bulk input and output filter
capacitors are needed to finish the design. The LTM8051
product video is available on website.
