ZHCSD04E November 2014 – March 2022 TPS65400
PRODUCTION DATA
The PAGE command provides the ability to configure, control, and monitor multiple outputs on a single TPS65400 using a single PMBus physical address. All subsequent commands that depend on PAGE are applied to the rail selected by the PAGE command.
Rails are numbered starting with one, while pages are numbered starting at 0. Table 8-8 shows the relationship between the PMBus PAGE value and the rail number.
| BITS | NAME | READ / WRITE | DEFAULT VALUE | VALUE | OUTPUT RAIL | PAIRING | CURRENT SHARING RELATIONSHIP |
|---|---|---|---|---|---|---|---|
| 7:0 | PAGE | R/W | 0xFF | 0x00 | SW1 | SW1-SW2 | Master |
| 0x01 | SW2 | Slave | |||||
| 0x02 | SW3 | SW3-SW4 | Master | ||||
| 0x03 | SW4 | Slave | |||||
| 0x04 to 0xFE | Invalid | — | — | ||||
| 0xFF | All | — | — |
On the TPS65400, current share is organized in pairs (PAGE = 0x00, 0x01 and PAGE = 0x02, 0x03). When current sharing mode is detected on a particular pair, the slave PAGE is invalid and the slave’s default settings follow that of its master PAGE. The only exception is that the slave switcher PWM will be a fixed 180° phase-shift from its master (see (D7h) FREQUENCY_PHASE). Additionally, the ISHARE bit will be asserted (see (D6h) IOUT_MODE).
(00h_ PAGE of the register map describes the PAGE command in more detail.
The PAGE parameter is not stored in the default store in data flash.
