Power Supply Design Integration Levels Level 1 Integration: On/Off Control At Level 1, electronic intelligence augments a standard analog design. The intelligence provides limited On/Off control functions such as start-up sequencing, automatic shutdown and watchdog fault detection functions. More sophisticated solutions can provide logging functions for later failure analysis, remote communication and customized thermal control algorithms.
Power Supply Design Integration Levels Level 3 Integration: Topology Control This level permits the standard analog design to be reconfigured in addition to Level 1 and Level 2 features. Changing the analog loop configuration and swapping between two different analog control loop filters can be achieved. For example, a power supply can change from a PWM control loop to a hysteretic control loop at light loads.
Power Supply Design Integration Levels Moving to a Higher Level: Level 4 Full Digital Control Full digital control replaces the standard analog control loop design and also provides the power management functions of Levels 1-3 integration. The power supply regulation function is directly controlled by the digital circuits on the processor and the software running on the processor.
Power Supply Design Integration Levels The features of the dsPIC DSC devices enable full digital control of applications such as this AC-DC converter. The high-speed PWM module with multiple advanced operating modes helps implement various advanced conversion stages such as PFC, phase shift zero voltage transition converter with fullbridge conversion and synchronous rectification and multi-phase buck converters.
Which MCU or DSC Should You Choose? Microchip Provides Many 8-bit Devices That Can Be Used In Power Supply Applications PIC12F and PIC16F Microcontroller Product Families Microchip makes many families of 8-, 16- and 32-bit MCU and 16-bit DSC solutions that can be used in various intelligent power applications, enabling a designer to support the level of digital integration and performance required for the application.
