Vishay Increases Power Density for POL Converters With the Industry’s Smallest 6 A, 20 A, and 25 A Buck Regulator Modules

Vishay Intertechnology announced new 6 A, 20 A, and 25 A microBRICK® synchronous buck regulator modules designed to deliver increased power density and efficiency for point of load (POL) converters. Offered in a 10.6 mm by 6.5 mm by 3 mm package, the Vishay Siliconix SiC931, SiC951, and SiC967 are the smallest such devices on the market — with the lowest height — and feature wide input voltage ranges from 4.5 V to 60 V.

Up to 69 % smaller than other solutions, the regulator modules each offer two high performance MOSFETs, an inductor, and a controller, with only minimal external components needed for configuration and loop compensation. The devices’ compact size dramatically increases power density, while their high level of integration reduces design complexity and time to market. The regulators’ controllers consume minimum quiescent current, enabling peak efficiencies of up to 97 %. In data centers, the telecom infrastructure, and industrial applications, microBRICK regulators help reduce energy consumption by more efficiently delivering power to FPGAs, ASICs, and SoC core power supplies (more info).
