Description

The PT4680 Excalibur™ Series is a dual-output isolated DC/DC converter that combine state-of-theart power conversion technology with unparalleled flexibility. Operating from a (24V) industry standard input bus, the PT4680 series provides up to 20 ADC of output current from two independently regulated voltages (each output 15 ADC max).

The PT4680 series is characterized with high efficiencies and ultra-fast transient response, and incorporates many features to facilitate system integration. These include a flexible "On/Off" enable control, outputcurrent limit, over-temperature protection, and an input under-voltage lock-out. In addition, both output voltages are designed to meet the power-up/power -down sequencing requirements of popular DSP ICs.

The PT4680 series is housed in space-saving solderable copper case.

The package does not require a heatsink and is available in both vertical and horizontal configurations, including surface mount. The 'N' configuration occupies less than 2 in² of PCB area.
