DES CRIPT ION
The voltage mode, synchronous buck controller is designed
for point-of-use dc/dc conversion in high performance server
and desktop computers. High efficiency is accomplished at full
load by driving high- and low-side n-channel MOSFETs. The
input voltage range has been designed for 4.75 V to 13.2 V to
allow use of either 5 V or 12 V. The 1-MHz switching
frequency combined with the 10-MHz error amplifier provides
ultra-fast transient response necessary in a high performance
microprocessor power supply.
Si9142 is available in a 20-pin SOIC wide-body package and
specified to operate over the commercial (0
°
to 70
°
C)
temperature range.
A demo board, Si9142DB, is available.
