EV2499A-QB-00A 5-36V, 3A Step-Down Converter Evaluation Board QFN-13
The MPS EV2499A-QB-00A is an evaluation board built around the MP2499A for bench characterisation of the device in its intended topology. It operates from a 5 V to 36 V input, is rated for 3 A and switches at 270 kHz. The board carries the device in its QFN-13 package.
The EV2499A-QB-00A is an evaluation board for MP2499A, a synchronous rectified, step- down module converter with built-in power MOSFETs.

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.
