ZHCSNC8A February 2021 – March 2021 TPS541620
PRODUCTION DATA
The TPS541620 is a highly-configurable device. It can be configured through pin strapping on the MODE1 and MODE2 pins. Table 7-1, Table 7-2, and Table 7-3 show what aspects of the device can be configured by the respective mode pins.
| PIN | FUNCTION 1 | FUNCTION 2 |
|---|---|---|
| MODE1 | Phase setting for single and multi phase operation | Compensation tuning on VOUT2 in dual-output conditions |
| MODE2 | Frequency and compensation tuning on output in multi-phase operation or VOUT1 in dual-output operation |
| RESISTOR FROM MODE1 TO AGND (k?) | OPERATION MODE | PHASE POSITION FOR CHANNEL 1 | PHASE POSITION FOR CHANNEL 2 | RAMP CAPACITOR FOR VOUT2 (pF) | NOTES |
|---|---|---|---|---|---|
| 10.7 | In two-phase configuration | 0° | 180° | Sets phase positions for the two outputs of the device. | |
| 15.4 | Dual-output independent single phase | 0° | 180° | 1.5 | Sets phase position for both channels in dual-output independent single phase operation to 0° and 180°. Sets ramp capacitor value for VOUT2. |

| 19.6 | 4 | ||||
| 22.1 | 6 | ||||
| 24.9 | Dual-output independent single phase | 90° from Sync | 270° from Sync | 1.5 | Sets phase position for both channels in dual output independent single phase operation to 90° and 270°. Sets ramp capacitor value for VOUT2. |
