EV1477H-TF-00B 4.2-17V, 3A High-Efficiency Evaluation Board SOT563
The MPS EV1477H-TF-00B is an evaluation board built around the MP1477H for bench characterisation of the device in its intended topology. It operates from a 4.2 V to 17 V input, is rated for 3 A and switches at 1.2 MHz. The board carries the device in its SOT563 package.
The EV1477H-TF-00B Evaluation Board is designed to demonstrate the capabilities of MPS' MP1477H, a fully-integrated high- frequency, synchronous rectified, step-down, switch-mode converter with internal 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.
