EV158-S-00A Universal Input Non-Isolated Off-Line Regulator Evaluation Board TSOT23

The MPS EV158-S-00A is an evaluation board built around the MP158 for bench characterisation of the device in its intended topology. The board carries the device in its TSOT23 package.

The EV158-S-00A Evaluation Board is designed to demonstrate the capabilities of MP158.

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.
