ZHCSNL3A December 2021 – November 2023 TPSM8D6C24
PRODUCTION DATA
The resistor divider for the ADRSEL pin selects the range of PMBus addresses and SYNC direction for the TPSM8D6C24. For standalone devices with only one device supporting a single output voltage, the ADRSEL divider also selects the phase shift between SYNC and the switch node.

The resistor to AGND for ADRSEL programs the device PMBus target device address according to Table 6-15:
| Resistor to AGND Code | Target Device Address (16-31 Range) | Target Device Address (32-47 Range) |
|---|---|---|
| 0 | 0x10h (16d) | 0x20h (32d) |
| 1 | 0x11h (17d) | 0x21h (33d) |
| 2 | 0x12h (18d) | 0x22h (34d) |
| 3 | 0x13h (19d) | 0x23h (35d) |
| 4 | 0x14h (20d) | 0x24h (36d) |
| 5 | 0x15h (21d) | 0x25h (37d) |
| 6 | 0x16h (22d) | 0x26h (38d) |
| 7 | 0x17h (23d) | 0x27h (39d) |
| 8 | 0x18h (24d) | 0x48h (72d) |
| 9 | 0x19h (25d) | 0x29h (41d) |
| 10 | 0x1Ah (26d) | 0x2Ah (42d) |
| 11 | 0x1Bh (27d) | 0x2Bh (43d) |
| 12 | 0x1Ch (28d) | 0x2Ch (44d) |
| 13 | 0x1Dh (29d) | 0x2Dh (45d) |

| 15 | 0x1Fh (31d) | 0x2Fh (47d) |
When a TPSM8D6C24 device is configured as the loop controller of a multi-phase stack, it will always occupy the zero-degree position in (37h) INTERLEAVE, but the ADRSEL resistor divider can still be used to select Auto Detect, Forced SYNC_IN, and Forced SYNC_OUT. When the loop controller of a multi-phase stack is configured for SYNC_IN, all devices of the stack remain disabled until a valid external SYNC signal is provided.
