Vishay Intertechnology’s SiC45x family of microBUCK® synchronous step-down regulators awarded 21IC 2021 award for Top 10 Power Products


MALVERN, Pa., September 24, 2021 (GLOBE NEWSWIRE) – Vishay Intertechnology, Inc. (NYSE: VSH) today announced that its Vishay Siliconix SiC45x family of microBUCK® Synchronous step-down regulators have been named by 21IC as the 2021 Top 10 Power Product Award winners. Delivering output currents of up to 40 A in the compact PowerPAK® With a 5mm by 7mm housing, the devices were awarded in recognition of their increased power density and transient response compared to previous generation regulators.

Now in their 19th year, the Top 10 Power Product Awards have become the industry benchmark for innovative energy products. Voted by engineers and selected by editors of 21IC after careful review, the award-winning products were chosen based on their technological innovation, energy efficiency, ease of application development and market response.

The high power density of SiC45x devices is made possible by the co-packaging of high performance n-channel trench MOSFETs with a PWM controller in a compact package. The regulators provide low operating current in standby mode, allowing maximum efficiency of up to 98% and reducing power loss. Intended to simplify the design of high-performance point-of-load converters (POL), integrated devices require minimal external components for configuration and loop compensation.

The regulators of the SiC45x family offer nominal currents of 15 A, 25 A and 40 A with input voltages of 4.5 V to 20 V. They are internally compensated over the entire VIN and VOUTSIDE operating range. Highly configurable, the devices combine their wide input voltage range with an adjustable output voltage of 0.3 V to 12 V. The extremely versatile regulators are ideal for a wide range of applications, including POL converters in the cloud computing, corporate servers and industrial computers, in addition to networking, telecommunications and storage systems.

The top 10 power products were awarded on September 15 at a ceremony at the 2021 21IC Power Supply Technology seminar in Beijing. Sherry Huo, Senior Product Application Engineer (Power IC, Siliconix Division) at Vishay China, accepted the award on behalf of Vishay. The full list of winners is available at
