Equipment
5.3.1
Power Supplies
TI recommends the following or similar DC power supplies for tests:
•
At least up to 6-V and 1-A power supply for powering the EVM, for example: BK Precision, series 1715
•
At least up to 1000-V and 1-A power supply for powering the power stage at the system level
evaluation, for example: Glassman FL1500 1.0
5.3.2
Function Generator
One 2-channel function generator over 20 MHz, for example: Tektronix AFG3102
5.3.3
BNC Feed-Thru Terminator
Two 50-
Ω
BNC male to female feed-thru terminators DC to 1 GHz, for example: Tektronix 011-0049-02
5.3.4
Oscilloscope
Oscilloscope 500-MHz or higher with four channels, for example: Tektronix DPO7104
5.3.5
Oscilloscope Probes
•
At least 500-MHz bandwidth passive voltage probe, for example: Tektronix P6139A
•
Two, at least 200-MHz bandwidth, 1000-V common mode differential voltage probes, for example:
Tektronix THDP020
•
At least 50-MHz bandwidth current sense probe, for example: Tektronix TCP202
5.3.6
Digital Multi-Meters
Two digital multi-meters for evaluation of the EVM alone, and four digital multi-meters for evaluation on the
system level with a buck converter: for example Fluke 187
