PRODUCT OVERVIEW

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

rectiﬁ er, forward topology, UHEs boast 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, UHEs

provide stable no-load operation, excellent line

(±0.1%) and load (±0.15%) regulation, quick step

response (200μsec), and low output ripple/noise

(50-100mVp-p). Additionally, the UHEs unique

output design eliminates one of the topology’s few

shortcomings–output reverse conduction.

Taking full advantage of the synchronous-

requirements from 9 to 75 Volts.

... If the short-circuit condition persists, another shutdown cycle will be initiated. This on/off cycling is referred to as “hiccup” mode. The hiccup cycling reduces the average output current, thereby preventing internal temperatures from rising to excessive levels.

... Applying an external voltage to pin 4 when no input power is applied to the converter can cause permanent damage to the converter. Trimming Output Voltage UHE converters have a trim capability (pin 9) that allows users to adjust the output voltages ± (±10% for T models). Adjustments to the output OUT voltages can be accomplished via a trim pot (Figure single ﬁ ...
