standard 2" x 2" pinout, DATEL's new UHE Series DC/DC Converters deliver more

current/power (up to 10A/30W) than currently available from either package size.

The UHE 12-30W Series of high-efﬁ ciency, isolated DC/DC's provide output power

ranging from 10 Amps @ 1.2V to 2 Amps @ 15V. Offering both 2:1 and 4:1 input

voltage ranges, UHE's meet V

outstanding efﬁ ciency (some models exceed 91%) enabling full-power operation to

ambient temperatures as high as +60°C, without air ﬂ ow. Assembled using fully

automated, SMT-on-pcb techniques, UHE's provide stable no-load operation, excel-

lent line (±0.1%) and load (±0.15%) regulation, quick step response (200µsec), and

low output ripple/noise (50-100mVp-p). Additionally, the UHE's unique output design

eliminates one of the topology's few shortcomings–output reverse conduction.

outputs), output current limiting, short-circuit protection, and thermal shutdown.
