PAC
Phased Array Controller
Part number 19077
Features
Enhances performance of parallel converter arrays
Reduces peak reflected input ripple current and
output ripple voltage
Multi module control in a single SOIC package
Autoconfigures for up to twelve modules
Internal watchdog circuit for fault detection
Description
The Phased Array Controller (PAC) integrated circuit enhances
the performance of large power sharing arrays of modular
DC-DC converters. This device is intended for processing load
share signals on the parallel bus of Vicor Maxi, Mini, Micro
Series converters. Utilization of the PAC forces equal
separation in time of power conversion pulses produced by
each module in the array, thereby substantially reducing the
peak magnitude of input reflected ripple current and output
ripple voltage. Input and output filter requirements are reduced
accordingly, yielding a significant impact on cost and complexity
of the overall power conversion system.
