Module DC-DC 2-OUT 5V/3.3V 15A 26-Pin SIP Module

The PT4681 Excalibur Seriesis a dual-output isolated DC/DCconverter that combine state-of-theartpower conversion technology withunparalleled flexibility. Operatingfrom a (–24V) industry standard inputbus, the PT4681 series provides up to20 ADC of output current from twoindependently regulated voltages(each output 15 ADC max).The PT4681 series is characterizedwith high efficiencies and ultra-fasttransient response, and incorporatesmany features to facilitate systemintegration. These include a flexible“On/Off” enable control, output current limit, over-temperature protection,and an input under-voltagelock-out. In addition, both outputvoltages are designed to meet thepower-up/power -down sequencingrequirements of popular DSP ICs.The PT4681 series is housed inspace-saving solderable copper case.The package does not require aheatsink and is available in bothvertical and horizontal configurations,including surface mount. The‘N’ configuration occupies less than 2in² of PCB area.
