EV2481-H-00A 6-36V, 1.2A White LED Driver Buck/Boost Halogen Replacement Evaluation Board MSOP8
The MPS EV2481-H-00A is an evaluation board built around the MP2481 for bench characterisation of the device in its intended topology. It operates from a 6 V to 36 V input, is rated for 1.2 A and switches at 1.4 MHz. The board carries the device in its MSOP8 package.
The EV2481-H-00A is a Buck converter evaluation board for the MP2481, a wide input step-down converter designed for driving high-power white LEDs with up to 1A capability.

Design Notes
- The board ships in a default configuration; check the jumper and resistor options against the user guide before applying power.
- Respect the input terminal rating — most faults on evaluation boards come from an supply above the marked limit.
- Test points on the switching node and output are for a short-ground probe, not for a long oscilloscope lead.
- Where a GUI is supported, connect the dongle before power-up so the device enumerates on the I²C bus.
