UNR D5/D12 Series

Single Output, Non-Isolated, 5 or 12VIN to 1.8/2.5/3.3VOUT

8 and 10 Amp DC/DC Converters

vides a complete line of non-isolated DC/DC converters to satisfy this requirement.

With input voltages of 5V (-D5 models) and 12V (-D12 models) these converters

offer standard output voltages of 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.

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 for SMT package

High efﬁciency to 91%; Low noise

200kHz 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-recov-

ery). 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 Murata Power Solutions’ 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.
