Vishay Releases Siliconix SiC45x Family of 15A, 25A, and 40A Devices

Vishay announced it has enhanced its microBUCK synchronous buck regulators with the Siliconix SiC45x family of 15A, 25A, and 40A devices. The devices feature input voltages from 4.5 V to 20 V in the thermally enhanced 5 mm by 7 mm PowerPAK MLP34-57 package.

Further, the devices also feature high performance n-channel trench MOSFETs with a PWM controller.

They also boast a peak efficiency up to 98%.

The regulators are internally compensated via the VIN and VOUT range of operation. On top of this, they’re highly configurable with a wide input voltage range and an adjustable output from 0.3V to 12V.


According to a company press release, the regulators serve their purpose in a wide range of applications including POL converters in cloud computing, enterprise servers, and industrial computers, in addition to networking, telecom, and storage systems.

The SiC45x family devices also feature programmable switching frequencies from 300 kHz to 1.5 MHz and three operating modes.

Vishay noted that reliable operation is guaranteed thanks to the integration of a robust set of protection and monitoring features, including output over- and undervoltage protection (OVP / UVP), overcurrent protection (OCP) in pulse-by-pulse mode, differential output remote sensing, and over temperature protection (OTP) with hysteresis.
