Description

The PT4471 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 30A of output current over the programmable voltage range of 1.3V to 3.5V.

This represents a full 100W output at 3.3V.

The modules PT4471 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 applications requiring power supply redundancy, multiple PT4471 modules may connected for operation in an 'N+1' configuration. Each PT4471 connected will share the load current with other active PT4471 modules.
