epc9143-power-advanced-voltage-mode-control, release v2.2.0
Features Added\Updated
In this release the buck converter device driver was upgraded supporting the following new features:
- Average Current Mode Control Startup Current LImit
- Improved integration of Dynamic Over Current Protection Management
- Support for Synchronous and Asynchronous operation
The changes introduced by the buck converter device driver upgrade do not affect this firmware. The modified and extended features have been upgraded to support users who want to migrate/change the control loop of this firmware to average current mode control.
Bugfixes
- Current Sense Calibration
the averaging procedure of the current sense feedback offset compensation averaged over a data array which was one step too short. Hence the produced result was slightly lower than the real signal offset value resulting in a less effective offset compensation. - Operational Amplifier Configuration
this bug caused previously configured op-amp instances to be reset when a new instant was initialized. This bug did not affect the previous version of this firmware but may corrupt firmware where users may want to configure a second instance.
Documentation Update
The online documentation provided with this firmware was updated to account for the changes mentioned above. In addition, in this version also introduced additional chapters about the controller implementation and more detailed documentation of the NPNZ controller object classes used as feedback loop controllers.
