MAX5066 Evaluation Kit
2 _______________________________________________________________________________________
Recommended Equipment
5V to 16V power supply
Two loads capable of sinking 10A each
Digital multimeters (DMMs)
100MHz dual-trace oscilloscope
Quick Start
1) Ensure that the circuit is connected correctly to the
supplies and loads prior to applying any power.
2) Verify that the shunts are across:
JU1 pins 1 and 2 (OUT1 enabled)
JU2 pins 1 and 2 (OUT2 enabled)
JU3 pins 2 and 3 (two-output, out-of-phase
operation)
3) Turn on the power supply and adjust the input
voltage to 12V.
4) Verify that the output voltages are V
OUT1
= 0.8V and
V
OUT2
= 1.3V.
