Description
T h e PT4483 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 20A of output current over the programmable voltage range of 4.6V to 5.7V. This represents a full 100W output at 5V. 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 applications requiring power s u p p l y redundancy, multiple PT4483 modules may connected for operation in an `N+1' configuration. Each PT4483 connected will share the load current with other active PT4483 modules.

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.
