For surface-mount applications requiring 15 Watts of power from 5V and 3.3V,

DATEL offers a new power sharing DC/DC converter capable of meeting your

output current requirements. The DSM-5/2.65-3.3/3-D48 (36-75V input), DSM-

5/2.65-3.3/3-D24 (18-36V input) and DSM-5/2.65-3.3/3-D12 (10-18V input) are fully

isolated DC/DC converters capable of delivering any combination of 5V and 3.3V

output current up to a combined total of 15 Watts of output power.

Housed in a 1" x 2" x 0.52" metal, surface-mount package coated with

electrically non-conductive ﬁnish, these converters are regulated by a 3.3V control

loop that provides load regulation of ±0.5% for 3.3V output and ±2% for 5V

output. All models include input Pi ﬁltering, input overvoltage and undervoltage

shutdown circuitry, output overvoltage protection, output short-circuit and current-

limiting protection, and thermal shutdown. All models provide trim capability and

an on/off control function or sync control. Fully synchronous output rectiﬁcation

provides high efﬁciency (86%) and a stable output under no-load conditions.

DSM power sharing modules offer low output ripple and noise perfor-

mance, 1500 Vdc isolation voltage, and are fully speciﬁed for –40 to +100°C

operation. These devices meet IEC950, UL1950 and EN6950 safety stan-

dards; CB reports are available on request. "D48" models are CE marked

(meets LVD requirements)
