2.5V (2A), 5V-to-3.3V (3A), and 12V-to-3.3V (3A) DC/DC converters in miniature,
1" x 1" surface-mount and through-hole packages. The "gull-wing" SMT packages
(with metal shells and non-conductive plastic baseplates) weigh a mere 17 grams
and can withstand lead temperatures up to +230°C. They are compatible with virtu-
ally all contemporary pick-and-place and solder-reflow processes.
every low-voltage, high-current CPLD, ASIC, DSP , etc. has its own "power plant"
right next to it. With isolated DC/DC converters inevitably residing at the edges of
boards in proximity with backplanes and power buses, the "on-board" proliferation
of distributed power will continue with more cost-effective, non-isolated devices.
The low-cost, easy-to-use (no external components required), highly reliable (100%
fully automated SMT construction) 3.6-10W UNR Series makes this power pro-
cessing at the concluding point of use a practical reality today.
optional on/off control (for power-sequencing requirements), output current limiting,
and short-circuit protection (foldback technique with auto-recovery). Additionally,
the 12V-to-3.3V models offer input undervoltage lockout (at 9.6V). Their impressive
guaranteed efficiencies enable all models to deliver their fully rated output power
from –40 to +65/70°C (ambient) without heat sinking or forced-air cooling.

high efficiency, ease-of-use, long-term reliability, and overall cost effectiveness will
impress you. Safety agency approvals are currently in progress.

"D5" models do not have input undervoltage shutdown.
"D5" models employ a more traditional buck-regulator design
in which this FET is replaced with a power Schottky diode.
