Digitally-Enhanced
Power Analog Control
Microchip’s Digitally-Enhanced Power Analog family combines the power and performance of an analog-based controller with the flexibility of a digital interface.
These products maintain the fast and efficient analog feedback loop and incorporate a digital front-end. This digital front-end offers configurability, including the ability to include custom algorithms, as well as a communication interface.
Key Benefits:
It's ANALOG–FAST! There's no digital controller or A/D in the feedback loop.
It's DIGITALLY–FLEXIBLE! The digital controller combines seamlessly with the analog controller, allowing on-the-fly adjustments to the operating points, loop compensation, protection limits, MOSFET dead time settings and many other features through its I²C™/PMBus™ interface.
It's INTEGRATED! In addition to the analog and digital controllers, a mid-voltage LDO and synchronous high-side and low-side MOSFET drivers are all integrated into a single package.
It's Simple! Development Tools are available to simplify the configuration and help analog engineers get up and running quickly in their application.
Ou seja, prevaleceu o bom senso
Um PWM Analógico é muito mais simples, a Resolução tende ao infinito.
Seria também o caso do Controlador PID, que é por natureza inerentemente Analógico
