Here's a miniature BEC for micro and very small aircraft. The BEC features an adjustable voltage output of 1 - 15 Volts. The output voltage is adjusted via the small potentiometer on the PC board (see pics). The input voltage range is 5 - 18 Volts.
Note: Take care not to touch the output wires together when energized or the unit will burn-out. (Like most any BEC.)
The MP1482 is a monolithic synchronous buck regulator. The device integrates two 130mΩ MOSFETs, and provides 2A of continuous load current over a wide input voltage of 4.75V to 18V. Current mode control provides fast transient response and cycle-by-cycle current limit.
This listing is for the PC board only. The board does not come with wire or plugs.
