APC18 Series

75 Watt (18 Amp) Non-Isolated DC-DC Converters

The APC18 series of non-isolated DC-DC converters comprises two models with different input and output ratings to satisfy a broad diversity of semiconductor power needs.

The APC18T04 accepts a 3 to 5.5 Vdc input and produces an output that can be trimmed from 0.75 to 3.6 Vdc. Rated at 60 watts, it has a typical efficiency of 95% and can deliver up to 18 amps.

The APC18T12 accepts a 10.0 to 14.0 Vdc input and produces an output that can be trimmed over a very wide 0.75 to 5.5 Vdc range. Rated at 75 watts, it has a typical efficiency of 92% and can deliver up to 18 amps.

All APC18 series converters feature input undervoltage lockout, remote On/Off and remote sense facilities as standard, as well as comprehensive protection against short-circuit and overtemperature conditions. Packaged as low profile surface-mount modules, they have a footprint of just 0.56 x 1.3 inches (14.2 x 33 mm).
