in a series of DOSA compliant, digitally controlled
DC-DC converters that are based on a 32-bit ARM
processor. The DSQ series provides a fully regu-
lated, digitally controlled DC output in a ¼-brick
format that will support the DOSA industry standard
footprint for isolated board mounted power mod-
ules. The DSQ series supports advances in power
conversion technology including a digital interface
supporting the PMBus protocol for communications
to power modules. The DSQ0150V2 is an isolated,
regulated, 600W-12Vout quarter brick that sup-
ports the TNV input voltage range of 36V–75V with
a typical efficiency of 96%. The DSQ series also
incorporates a “droop” load sharing option that
allows connecting two or more units together in
parallel for demanding power-hungry applications
or to provide redundancy in high reliability applica-
tions. The converter also offers high input to output
isolation of 2250 VDC as required for Power over
Ethernet (PoE) applications. The DSQ series is suit-
able for applications covering MicroTCA, servers
and storage applications, networking equipment,
Telecommunications equipment, Power over Ether-
net (PoE), fan trays, wireless networks, wireless pre-
amplifiers, and industrial and test equipment, along
with other applications requiring a regulated 12V.

Notes:
[1] Typical at TA=+25°C under nominal line voltage and full-load conditions. All models are specified with an external 1μF multi-layer ceramic and 10μF capacitors across their output pins.
[2] Over-current protection is non-latching with auto recovery (Hiccup).
[3] Regulation specifi cations describe the output voltage changes as the line voltage or load current is varied from its nominal or midpoint value to either extreme.
