INNOVATION and EXCELLENCE

Single Output

UNR Series

Non-Isolated, 1.2/1.5/1.8/2.5/3.3VOUT

8 and 10 Amp DC/DC Converters

As supply voltages trend lower and load currents increase, centralized power

becomes more impractical. The tight accuracy, low noise and quick transient

response demanded by today's low voltage CPU's, ASIC's and DSP's make power

processing at the point of use the only viable solution. The UNR 12-33W series

provides a complete line of non-isolated DC/DC converters to satisfy this require-

ment. With input voltages of 5V (-D5 models) and 12V (-D12 models) these convert-

ers offer standard output voltages of 1.2, 1.5, 1.8, 2.5 and 3.3 Volts and up to

10 Amps of output current in both through-hole and surface-mount 1" x 2" metal

cases.

Features

Input ranges of 4.75-5.5V or 10.8-13.6V

Output voltages of 1.2/1.5/1.8/2.5/3.3V

8 and 10 Amp output current models

V^OUTuser-trimmable from 1.28V to 3.6V

Non-isolated, full synchronous topology

1" x 2" through-hole or SMT package

With on/off control and output voltage trim capability as standard features, these

non-isolated converters exploit full synchronous rectiﬁcation, planar magnetics, and

100% automated assembly to deliver high efﬁciencies (to 91%) and low noise at

low cost.

Gull-wing leads/standard reﬂow for SMT

High efﬁciency to 91%; Low noise

340kHz switching; Planar magnetics

These versatile DC/DC’s are fully line and load regulated. They feature quick

transient response (50µsec), user-optional on/off control (for power sequencing),

and output overcurrent detection and shutdown ("hiccup" technique with auto-

recovery). Their impressive guaranteed efﬁciencies enable them to deliver fully rated

output power from –40 to +50/55°C (ambient) without supplemental cooling.

If your high current requirements have made the use of inefﬁcient linear regula-

tors impractical, take a look at one of DATEL’s new switching buck regulators. Their

high efﬁciency, ease-of-use, long-term reliability, and overall cost effectiveness will

impress you. Safety agency approvals and EMC characterizations are currently in

progress.
