Description
T h e PT4482 ExcaliburTM 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 include a number of i n b u i l t 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 PT4482 may be operated with up to two P T 4 4 9 9 compatible booster modules. Each PT4499 adds an additional 30A of output current capability.

Notes: (1) The Inhibit (pin 3) has an internal pull-up, which if left open circuit allows the converter to operate when input power is applied. The open-circuit is limited to 6.5V. Refer to the application notes for interface considerations. (2) See Safe Operating Area curves or contact the factory for the appropriate derating. (3) The case pins on through-hole pin configuration (suffix A) must be soldered. For more information see the applicable package outline drawing.
