EV155-J-00A Energy Efficient Off-line Regulator EV Board Evaluation Board TSOT23

The MPS EV155-J-00A is an evaluation board built around the MP155 for bench characterisation of the device in its intended topology. The board carries the device in its TSOT23 package.

The MP155 is a primary-side regulator that provides accurate constant voltage regulation without the opto-coupler, and supports buck, buck-boost, and flyback topologies.

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.
