Up to 85% Efficiency
Triple Output, 25 watt converter
Available in 12, 24 and 48 VDC Inputs
Industry Standard 2” X 2” X 0.4” Package
Over Voltage, Over Temperature and Short Circuit
Protection
The 2500HN (high-density, non-encapsulated), triple output
power modules are 25 watt DC/DC converters available in a
triple output configuration providing both digital and analog
outputs in a compact, industry standard 2" X 2" X 0.4" package.
These 400kHz, switching converters are available in 12, 24 and
48 VDC inputs making them one of the most versatile product
lines in the market with efficiencies up to 85%. Advanced
surface mount construction allows these converters to
achieve outstanding thermal performance eliminating the need
for thermal potting compounds and thereby enhancing
manufacturing efficiency to reduce costs.
