Take Advantage of Vishay’s microBRICK Evaluation Board in element14’s Latest Roadtest

The element14 Community is offering another roadtest for community members and looking for some engineers and makers who would like to push the limits of their POL converters with increased power density and efficiency using Vishay’s microBRICK Synchronous Buck Regulator EVB module. According to Element 14, it will provide roadtesters with Vishay’s SiC967EVB-A synchronous buck regulator module, pay for everything, and testers will get to keep the module after posting a review on the element14 Community website.

Vishay’s SIC967EVB-A is a synchronous buck regulator module outfitted with power MOSFETs and an inductor capable of delivering 6 A of continuous current at up to 2 MHz switching frequency. The module provides an adjustable output voltage down to 0.8 V from 4.5 V to 60 V input rail to handle a myriad of applications, including home and industrial automation, transformer regulation, robotics, networking, battery management systems, vending machines, ATMs and more. What’s more, the SiC697 architecture supports fast transient response times with minimum output capacitance and tight ripple regulation at very light load.

The device is internally compensated; no external ESR network is required for loop stability purposes, and it incorporates a power-saving feature that increases light load efficiency. The regulator also offers a full protection feature set, including output over-voltage protection (OVP), cycle-by-cycle over-current protection (OCP), short circuit protection (SCP) and thermal shutdown (OTP). The board is configured for 4.5 V to 50 V input, while output current capability is model dependent, though the operating range may be modified by changing components such as the mode or feedback resistor.

According to Vishay, the SiC967EVB-A can operate in forced continuous conduction mode or power save mode. In forced continuous conduction mode, the module features a set of implementations to eliminate LS re-circulating current and switching losses. The integrated internal zero crossing detector (ZCD) monitors PHASE node voltage to determine when inductor current starts to flow on the negative side. In power saving mode, when the inductor valley current hits below zero, the module deploys diode emulation mode by turning off the LS FET. If the load further decreases, the switching frequency is reduced proportionally to the load condition to save switching losses.

element14 Community’s microBRICK Synchronous Buck Regulator EVB RoadTest is currently open to five more participants, with the enrolment ending date coming up fast on the 31^st of October. Those looking to enter should do so while those positions are still open. Good Luck and happy building!
