Description
The NXA025 series SMT (surface-mount technology) power modules are non-isolated dc-dc converters that can
deliver up to 25A of output current with full load efficiency of 93% at 3.3Vdc output voltage. These modules provide
a precisely regulated output voltage from 0.8Vdc to 5.5Vdc, programmable via an external resistor. Their open-
frame construction and small footprint enable designers to develop cost- and space-efficient solutions. Standard
features include remote On/Off, adjustable output voltage, remote sense, active current sharing between parallel
modules, output voltage sequencing of multiple modules, overcurrent, overvoltage, and overtemperature protection.
