Description
The NXA025 series SIP (single-in line package) 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. The 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, output voltage sequencing of multiple modules,
over current, over voltage, and over temperature protection.
