These DC-DC converters include full magnetic isolation with Basic insulation, up to 2250VDC. For powering digital systems, the outputs offer fast settling to step transients and will accept higher capacitive loads. Excellent ripple and noise specifications assure compatibility to noise-susceptible circuits. For systems requiring controlled startup/shutdown, an external remote on/off control may use a switch, transistor or digital logic.
A wealth of self-protection features avoid both converter and external circuit fails. These include input undervoltage lockout and overtemperature shutdown. The outputs current limit using the ‘hiccup’ autorestart technique and the outputs are short-circuit protected. Additional features include output overvoltage and reverse conduction elimination.
The UEI25-120-D48 series’ industry-standard pinout makes this part a direct replacement for larger 1 x 2 converters. Applications include small instruments, area-limited microcontrollers, data communications equipment, remote sensor systems, telephone equipment, vehicle and portable electronics. It operates in the industrial temperature range of -40 to +85degC.
