Evaluation Board Layout Image (6 layers) Instructions Caution: Observe all precautions while testing this evaluation board (wear safety glasses, do not connect potentially dangerous high voltages, be sure to not make incorrect reverse connections). Do NOT exceed a DC input voltage of 60V.
- Page 4 • Ex. Pull Enable2 high by connecting a jumper across top pins of JEN1. • Note: All enables are pulled high internally by NIS3071 if left floating. • Controlling Enables 1. Locate the 4 Test Points on the bottom of the board labeled TPEN1, 2, 3, and 4.
- Page 5 NIS3071 EVB Manual Multi-Channel Use • An additional functionality of the device is the ability to operate each channel independently of the others, each with their own input, output, enable, and protection. • Two Rail Configuration Test Parallel Channels 2 and 3 (inputs and enables) using jumpers as described in the above section.
- Page 6 NIS3071 EVB Manual Turn on Time • The turn on time (or slew rate) of the output can be adjusted by connecting a capacitor from the dvdt pin to ground. In this EVB’s case, there are 2 different capacitors to choose from that will show this functionality effectively.
