PI3323/PI3325 – High Efficiency ZVS Buck Regulators with 22A Continuous Current

Vicor has released two new ZVS buck regulators, the PI3323 and PI3325 that provide up to 22A of continuous operation and up to 96% peak efficiency. These new devices have an extended operating temperature range of –55 to +120°C and an optional tin-lead 10 x 14mm SiP BGA package for Mil COTS applications.

The high-density and high-efficiency buck regulators are easy to parallel for higher power delivery and have a 14 – 42V input voltage range and support nominal outputs of 3.3V and 5V, adjustable over ranges of 2.2 – 4V and 4 – 6.5V, respectively.
