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