UNR-3.3/3-D5-C Product Details
PRODUCT OVERVIEW
Murata Power Solutions' 3.6-10W UNR Series consists of non-isolated, 5V-to-1.8V (2A), 5V-to2.5V (2A), 5V-to-3.3V (3A), and 12V-to-3.3V (3A) DC/DC converters in miniature 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 virtually all contemporary pick-and-place and solder-refl ow processes.
The true benefi ts of distributed power will ultimately be realized only when 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 processing at the concluding point of use a practical reality today.
These versatile DC/DC's are fully line and load regulated. They feature user-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 effi ciencies enable all models to deliver their fully rated output power from –40 to +65/70°C (ambi-ent) without heat sinking or forced-air cooling.
If you've already considered and rejected the use of ineffi cient, step-down, linear regulators, take a look at one of these new switching buck regulators. Their high effi ciency, ease-of-use, longterm reliability, and overall cost effectiveness will impress you. Safety agency approvals are currently in progress.
