Description

The PT4476 Excalibur™ DC/DC converter module combines state-of-theart power conversion technology with un-paralleled flexibility. Incorporating high efficiency and ultra-fast transient response, these modules provide up to 8.5A of output current over the programmable voltage range of 6.5V to 17.5V.

The modules include a number of inbuilt features to facilitate system integration. These include a foldback output current limit, over-temperature protection, and an inhibit on/off control.

A differential remote sense is also provided to compensate for voltage drop between the converter and load.

For additional output current, one PT4476 may be operated with up to two PT4493 compatible booster modules.

Each PT4493 adds an additional 8.5A of output current capability.
