If your DSP and CPLD core logic are demanding more 1.5V, 1.8V or 2.5V

Features

current from your 3.3V system, don’t pay to derive more isolated power from your

intermediate dc bus. Murata Power Solutions’ new, 3.3V-input, UNR "D3" models

derive 10 Amps

■

3.0-3.6V input range; Non-isolated

1.5V, 1.8V or 2.5V output @ 10A

2" x 1" through-hole or SMT package

Gull-wing leads for SMT package

Full synchronous-rectiﬁer topology

300kHz switching; Planar magnetics

High efﬁciency, to 89%

of low-voltage current right from your 3.3V supply. These non-isolated power

converters exploit full synchronous rectiﬁcation, planar magnetics, and 100% auto-

mated assembly to deliver high efﬁciencies (to 89%), low noise (typically 80mVp-p),

and low costs. Housed in 1" x 2" shielded metal cases, UNR D3’s offer standard

through-hole ("T" models) or SMT ("SM" models) packaging.

The new "gull-wing" SMT packages (with metal shells and non-conductive

plastic baseplates) weigh less than 40 grams and can withstand peak lead tem-

peratures up to +300°C.

These versatile DC/DC’s are fully line ( 0.1% max.) and load ( 0.5% max.)

regulated. They feature quick transient response (25µsec), 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 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.
