ZHCSN24A August 2019 – May 2021 TPS53676
PRODUCTION DATA
TPS53676 supports adaptive voltage positioning (AVP) through the VOUT_DROOP PMBus command. This feature is also referred to as the DC load line (DCLL) for the control loop. Use a non-zero DC load line to reduce output voltage set-point as a function of the load current, with a controlled slope. This feature is optional. Set the DC load line to 0.0 mΩ in applications which do not use a load line.
The DC load line provides two main benefits:
