50 A power supply module for FPGA and high-end processor systems

Intersil Corporation launched compact and fully encapsulated digital DC/DC PMBus power module of size 18mm x 23mm x 7.5mm with a current rating of 50 A. The compactness and size is the real interesting feature of this module, with the size nearly equivalent to a high capacitance aluminum electrolytic capacitor which are commonly used in DC/DC converters of older tech. The ISL8272M operates from input voltage source of 12/5 volts DC power bus/rails. These modules can be connected in parallel to achieve higher current rating up to 200 A. ISL8272M is suggested for FPGAs, ASICs, processors and memory in space-constrained and power-dense telecom and datacom applications. The device is also well suited for high-end instrumentation, industrial and medical equipment. ISL8272M uses PMBus for sequencing and system monitoring. ISL8272M keeps output power supply stable even due to change in performance of output capacitor due to temperature, variation or aging. The ISL8272M's ChargeMode control loop also provides a single clock cycle fast transient response to output current load steps common in FPGAs and DSPs processing power bursts. "Cloud computing's high availability demands are requiring systems to control and monitor every power rail to maximize efficiency and reduce downtime," said Mark Downing, senior vice president of Infrastructure and Industrial Power Products at In...
