Current Sharing Controller for High Performance Processors
FEATURES
Automatic True Current Sharing with Parallel Converters
External SCR Drive for Fault Protection
Over-Voltage Protection
Programmable Over-Current Protection
Voltage Mode Control
Precision 1.3-V, ±1.6% Reference
DESCRIPTION
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.
Si9143 is designed to provide automatic true current sharing
with parallel power supplies. True current sharing reduces
stress on a single supply and increases system reliability. The
system reliability is further increased by short circuit
protection and external SCR drive signal to disconnect the
power supply during fault conditions.
Si9143 is available in a wide-body 24-pin SSOP package and
specified to operate over the commercial (0
°
to 70
°
C)
temperature range.
A demo board, Si9143DB, is available.
