The IP3128XXX-04 series is a family of high performance DC-DC power modules
designed for aerospace, military and high-end industrial applications.
These modules feature a fixed 400kHz switching frequency and deliver excellent
reliability, low noise, and high power density. All models are optimized
for a nominal 28 volt input within a voltage range of 16-40 volts. Single,
dual and triple outputs of 5, 12, 15 volts are available. Typical applications
do not require an external heat sink as long as the designer ensures that
the case temp does not exceed -55°C to 105°C (M grade) or -40°C up to 85°C
(I grade). All the modules are designed with LC network filters to minimize
reflected input current ripple and output voltage ripple.
The modules include a soft-start, and short circuit protection circuitry to ensure critical module protections. The soft-start feature ensures that high inrush currents commonly seen during start-up are effectively controlled to prevent damage to the converter. The short circuit protection completely protects the modules against short-circuits of any duration by a shutting down and restores to normal when the overload is removed. The modules are potted with a thermally conductive compound and packaged in a metallic case to ensure the module’s integrity under high stress environmental conditions.
