As known to all, high power supply technology is mature, with outstanding functions and performance. But like rated voltage input power supply, because of its small size, it is hard to give consideration to short circuit function with outstanding performance, so the most of the manufacturers sacrifice efficiency and ripple to keep short circuit protection function, or sacrifice short circuit protection function in pursuit of so-called high efficiency and low ripple, etc.

The development of micro-power modules has been the difficulty of domestic and foreign power supply manufacturers.

B-XT-1WR2 is one of the latest generation of ultra-small SMD micro-power supply products released by Mornsun. It not only solves the problem of dilemma, but also means that micro-power supply technology has reached a new high level. This series of products have small volume of 12.75 x 8.30 x 7.00 mm with circuit protection function, and the efficiency is still higher than 80%. What’s more, so small volume of power have five original invention patents. These patents have solved some big problems perfectly in the history of the development of micro-power supply, such as: low-temperature start difficultly under low-temperature, bad short circuit under high-temperature or high input voltage, low efficiency under high and low temperature, low light-load efficiency, big noise which is hard to remove, etc.

B-XT-1 WR2 used the latest short circuit protection patent technology, revolutionized the traditional switching power supply short circuit protection mode, and filled the switching power in this theory blank.

In addition, through the core technology of new magnetic core structure design and the new circuit control theory, B-XT-1 WR2 has different performance with their colleagues:

1）Sustainable short circuit protection under -40℃-85 ℃

2）Start-up with capacitance load under -40℃

3）Stable efficiency under -40℃-105 ℃

4）Constant efficiency with all input voltage

5）Antistatic ability(8KV)

6）Perfect hot plug fuction

The traditional the rated voltage products with light load (20-30%) generally only have 50% of the efficiency, but B-XT-1 WR2 can easily reaches 60% or more, set B0505XT-1 WR2 (5 V input 5 V output) as an example, its efficiency is 61% with a 20% load and it’s higher than 66% if the output voltage is 24 V.

In the past, in order to make SMD products meet the requirements of the reflow process curve, almost all of the power supply manufacturers used high lead solder paste, but it cant satisfy the strict request of Rohs from partial enterprises, and B-XT-1 WR2 has really solved the problem of SMD Rohs request which provides a more reliable choice.
