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.

Featured reference designs

Low-voltage, low-noise power-supply reference design for ultrasound front end

This power supply is optimized to provide power to eight 16-channel receive AFE ICs for ultrasound imaging systems. This design reduces part count while maximizing efficiency by using single-chip DC-DC converter + LDO regulators.

High density PMBus buck converter with inductor mounted over the converter

This design utilizes inductor-over-converter mounting to achieve 30A conversion in 1" by 0.6" footprint. DCAP control provides a high speed control loop for applications with large, rapidly varying loads, such as microprocessors. 

180-W, dual-channel, step-down converter reference design with 97% efficiency for server PSU

This PSU design features switching frequency synchronization between the dual channels and true differential remote sense of the dual outputs to compensate for the line voltage drop.
