DC/DC Converter Delivers 3.3 VDC
Using 200 LFM airflow, Power-One’s SSQE48T25033 sixteenth-brick DC/DC converter supplies 3.3 VDC at 25 A with 100% of full-rated power available at 55°C and 22 A at 70°C. The 22.9 mm × 33 mm × 9.5 mm devices offer ±3% combined line, load, and temperature regulation; efficiencies of up to 93%, an input range from 36 VDC to 75 VDC, the capability to withstand a 100 V input transient for 100 ms, and include a DOSA-compliant through-hole-mount pinout. The UL94 V-0-rated units protect against hiccup-mode overcurrent, output overvoltage, input undervoltage lockout, and overtemperature shutdown, and interface and trim capabilities consist of remote sense, remote ON/OFF (positive or negative logic option), and 10%/-20% output voltage trim ranges. Pricing is $32 each in 1,000 quantities.
