Troubleshooting

11.1 Boost converter

The DC/DC converter on the HV board is a LM2733X 1.6 MHz boost converter with integrated switch.
Test point TP2 should show a voltage of 30 V. If this is not the case, check if TP3 shows the required
input voltage of 5 V.

11.2 Jumper

Table 1. Jumper

JUMPERS

DESCRIPTION

JP1

Tx2 voltage selector: bypass HV driver when placed in “LV” position

For default operation (use high voltage for both channels), place jumper on the following:

1. JP1.P2 and JP1.P3 – HV

Figure 12. Jumper

When placing the jumper in LV position (on pins 1 and 2), “TDC1000-HV Driver EN2” should be
unchecked in the GUI. Otherwise the UCC27531 will pull its output to ground.
