| ITEM | TYPE | NAME | DESCRIPTION |
|---|---|---|---|
| TP1 | T-H loop | SW | Power supply Switch Node |
| TP2 | T-H loop | CH-B | Measure loop stability |
| TP3 | T-H loop | CH-A | Measure loop stability |
| TP4 | T-H loop | V_sense + | Remote sense + |
| TP5 | T-H loop | V_sense – | Remote sense – |
| TP6 | T-H loop | Vout | Use this VOUT for efficiency measurements |
| TP7 | T-H loop | SYNC/RST | Input a sync signal from a clock source; or apply logic low signal to RESET VOUT to initial boot-up voltage set by VSET pin. Refer to the Datasheet for details. |
| TP8 | T-H loop | VDD | Supplies the internal circuitry |
