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).
