New Buck Regulators in BGA Package Converts 48V Direct to PoL

August 22, 2018

PI354x buck regulatorThe new PI354x-00-BGIZ is the latest addition to the 48V Cool-Power ZVS Buck Regulator portfolio, giving power designers a new Ball Grid Array (BGA) package option in addition to the existing LGA (Land Grid Array) packages. The family of PI354x buck regulators is designed for a wide range of designs leveraging higher voltage distribution, including: telecom, network infrastructure, datacenters, industrial, battery, and lighting applications.

Operating from 36VIN to 60VIN, the PI354x delivers a regulated output voltage ranging from 2.2V to 14V at up to 10A.  For applications requiring more current, the family supports paralleling using single wire current sharing without any additional components.

The PI354x Cool-Power ZVS Buck Regulator family leverages the high performance ZVS topology to convert 48V direct to Point-of-Load (PoL) without sacrificing performance. With step-down regulation from a higher voltage source in a single stage, engineers can deploy more efficient power distribution architectures, reduce I2R losses, and eliminate costly and inefficient intermediate conversion stages.

The new devices in BGA packaging are:

Part Number Package Input Voltage Range Nominal Output Voltage Current
PI3542-00-BGIZ 10.5 x 10.5mm BGA 36 – 60V 2.5V 10A
PI3543-00-BGIZ 10.5 x 10.5mm BGA 36 – 60V 3.3V 10A
PI3545-00-BGIZ 10.5 x 10.5mm BGA 36 – 60V 5.0V 10A
PI3546-00-BGIZ 10.5 x 10.5mm BGA 36 – 60V 12V 9A
