SWIFT™ Point-of-Load DC/DC converters

High-performance conversion for high-current, space-constrained applications

SWIFT DC/DC converters provide a fully-featured, high power density solution to the problem of increasing power requirements with shrinking available PCB area. With input voltages ranging from 3V to 20V and output current capability up to 40A, SWIFT is the go-to brand for powering a high-current, low-voltage digital load from a nominal 12V, 5V, or 3.3V input. 

High efficiency

Integrated low Rdson synchronous FETs utilized in SWIFT converters boost efficiency and reduce power dissipation to improve thermal performance.

High power density

As power requirements increase and PCB area shrinks, SWIFT delivers high output current capability with advanced packaging technologies in small solution sizes.

Fully-featured

High-performance features like PMBus capability and high regulation accuracy over line, load, and temperature are hallmarks of the SWIFT portfolio.
