High-current power module relies on digital controller for precision output voltage control
The BDP12-0.6S60R0 digital power module is a PMBus compliant, non-isolated step-down converter that is designed for today’s Communications and Computing
applications, and addresses the needs for small form-factor designs while providing high reliability and high performance.
Bellnix’s 60 A BDP is the first in a series of Bellnix Digital Power modules based on Powervation’s digital controller architecture that provides a total power solution in a low-profile, 10 mm, form-factor. The 60 A BDP uses Powervation’s PV3012 digital two-phase controller, and parallel BDP module operation is supported via Powervation’s DSS current sharing bus. This PMBus compliant module features precision measurement & telemetry reporting, a full-line of programmable power supply protection features, power good, and optional tracking function, all in a compact 32.8 mm x 23.0 mm ROHS compliant SMD package design.
The 60 A BDP module is the first Bellnix Digital Power module to use Powervation’s digital control technology. The module features accurate control of the output voltage, and the ability to parallel a second BDP module for even higher power delivery requirements. The low-profile, ultra-small footprint design provides a high efficiency, high-current modular solution that supports the needs of today’s space critical applications while providing the benefits and flexibility of a PMBus compliant digital power supply. The 60 A BDP provides high performance with an output voltage accuracy of ±0.5%. The 60 A BDP will support power designers of 28 nm, 20 nm, 16 nm and other advanced process FPGA , ASIC and ASSP solutions.
Powervation’s Auto-Control claims to be the industry’s leading intelligent auto-tuning technology. The patented adaptive compensation technology optimizes dynamic performance and system stability in real-time without requiring any noise injection or the drawbacks of periodic techniques. This is a key benefit for modules and other designs that drive unknown or variable output loads, and addresses the challenges of load parameter drift that occurs over temperature and time.
The BDP12-0.6S60R0 power module, GUI, and evaluation board are available now from Bellnix.
