Required Equipment
V
IN
power supply 6 V to 32 V, at least 240 W at the input voltage under test, or 40 A for the full load off a 6-V input
Electronic load to step for efficiency graphs, and for dynamic load testing such as Kikusui PLZ334WL
Low inductance dynamic load for the 3.3-V output if the load slew rates > 3 A / μs needed
Oscilloscope such as Tektronix MDO34 with TPP0500B 10 × voltage probes and 30-A TCP0030A current probe
Digital multimeters such as Fluke 87iii or 87V
For Bode plots: Vector Network Analyzer such as Bode 100 from OMICRON Lab
Thermal camera such as FLIR E75
Keysight 34970 data acquisition, switch unit along with calibrated 100-A and 50-A current shunts for efficiency measurements
