8.3.6 Differential Sense Amplifier and Feedback Divider

The TPSM8S6C24 includes a fully integrated, internal, precision feedback divider and remote sense. Using both the selectable feedback divider and precision adjustable reference, output voltages up to 6.0 V can be obtained. The feedback divider can be programmed to divider ratios of 1:1, 1:2, 1:4, or 1:8 using the (29h) VOUT_SCALE_LOOP command.

The recommended operating range of (21h) VOUT_COMMAND is dependent upon the feedback divider ratio configured (29h) VOUT_SCALE_LOOP as follows:

Table 8-1 (29h) VOUT_SCALE_LOOP and (21h) VOUT_COMMAND Recommended Range
RECOMMENDED VOUT RANGE (V)
10.5 to 0.75
0.50.5 to 1.5
0.251 to 3
0.1252 to 6

Setting (21h) VOUT_COMMAND lower than the recommended range can negatively affect VOUT regulation accuracy while setting (21h) VOUT_COMMAND above the recommended range can limit the actual output voltage achieved.

Note: If the regulation output voltage is limited by the recommended range of the current (29h) VOUT_SCALE_LOOP value, VOUT can be below the intended (43h) VOUT_UV_WARN_LIMIT or (44h) VOUT_UV_FAULT_LIMIT without triggering their respective warning or faults due to the limited range of the reference voltage.
