Single Output

USQ 20A Models

High-Density, Quarter-Brick

20 Amp, DC/DC Converters

For low-voltage, high-current power . . . in the smallest space . . . over the widest

temperature range . . . call on DATEL’s USQ Series 20 Amp "quarter bricks." Occupy-

ing the industry-standard package (1.45" x 2.28" x 0.40") and pinout, USQ’s house

their fully-synchronous, forward design topology in a "two-board" assembly crowned

with a heat-sink-compatible aluminum baseplate. This combination of outstanding

thermal and electrical efﬁciencies endows USQ’s with industry-leading, thermal-

derating performance. The 1.8V^OUTmodel, for example, delivers its full 20 Amps up to

+55°C with a mere 200 lfm air ﬂow.

1.2/1.5/1.8/2.5/3.3/5/12/15/18/24V

USQ’s achieve all the performance metrics required for contemporary, on-board

power processing: high isolation (1500Vdc), superior efﬁciency (to 91%), tight regula-

tion (to ±0.05% max. line and load), low noise (to 50mVp-p), quick step response

(200µsec), and an array of protection features. I/O protection includes input under-

voltage lockout and reverse-polarity protection, as well as output overvoltage pro-

tection, current limiting, short-circuit protection, and thermal shutdown. The USQ

functionality suite includes remote on/off control (positive or negative polarity), output

trim (+10/–20%), and output sense functions.

All USQ DC/DC’s are designed to meet the BASIC insulation requirements of

UL1950 and EN60950, and all 48 Volt models will carry the CE mark. Safety certiﬁca-

tions, as well as EMC compliance testing and qualiﬁcation testing (including HALT)

have been successfully completed. Contact DATEL for copies of the latest reports.

Input voltage ranges:

36-75V (48V nom.)

18-36V (24V nom.)

Synchronous rectiﬁcation yields high

efﬁciency (to 91%) and stable no-load
