High power density POL DC/DC converter modules with 6, 20, and 25 A o/p current

Vishay launched 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 released today 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. Highly configurable, the regulators combine their wide input voltage ranges with adjustable output voltages down to 0.3 V. In addition, the SiC931 features four programmable switching frequencies at 600 kHz, 1 MHz, 1.5 MHz, and 2 MHz, while the SiC967 and SiC951 offer adjustable switching...
