EV2169-RH-00A 2.7-6V, 1A Synchronous Buck Evaluation Board QFN-18

The MPS EV2169-RH-00A is an evaluation board built around the MPQ2169 for bench characterisation of the device in its intended topology. It operates from a 2.7 V to 6 V input and is rated for 1 A. The board carries the device in its QFN-18 package.

The EV2169-RH-00A is an evaluation board for the MPQ2169, an internally compensated, dual, PWM, synchronous, step-down regulator that operates from a 2.7V to 6V input and generates an output voltage as low as 0.6V.

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.
