Summary:
UCD3028 digital power supply is rich in functions, can complete the control of two independent power branches; software configuration is flexible, can achieve a variety of functions including a variety of fault detection and processing. This paper describes the software design of UCD3028 based on a 1/8 brick module product, including the acquisition and conversion of external analog signals, the acquisition and related settings of secondary current, the input voltage acquisition and related settings, and the output voltage. Acquisition and related settings, design and implementation of output voltage pre-biasing (Prebias) function, central interrupt module and interrupt function implementation, design and implementation of feedforward function, initialization of loop compensator (CLA), DPWM (digital pulse width) Initialization of modulation), initialization of general-purpose registers, introduction of clock initialization and state machine, introduction of internal memory devices, and finally a flow chart of the entire UCD3028 software.

A capacitance switch needs only one electrode to function. The electrode can be placed behind a non-conductive panel such as wood, glass, or plastic. The switch works using body capacitance, a property of the human body that gives it great electrical characteristics. The switch keeps charging and discharging its metal exterior to detect changes in capacitance. When a person touches it, their body increases the capacitance and triggers the switch.
Capacitance switches are available commercially as integrated circuits from a number of manufacturers. These devices can also be used as a short-range proximity sensor.
