UCC28880D is a monolithic, high-efficiency AC-DC power supply controller responsible for low-power, offline switching power supplies. It combines an adaptive digital control system with an embedded MOSFET driver, allowing for easier design, lower system costs, and reduced component count. It can work with the ultra-fast PFC integrated in NXP\'s LPC1300 family of microcontrollers, allowing for flexibility across a wide range of applications.
The UCC28880D excels in low-power, offline applications, such as consumer electronics and office equipment, providing reliable, compact AC-DC conversion. The UCC28880D achieves this through its adaptive digital control system, which continuously adapts to changing line and load conditions. This allows the controller to maintain a high efficiency and improve the power supply\'s THD. Additionally, the controller features an embedded MOSFET driver that can be connected to both standard and logic-level MOSFETs, further reducing component count and system costs. The controller also features multiple protections, such as over-temperature and short-circuit protection, ensuring reliable operation.
The UCC28880D features a high-voltage start-up and voltage switch controller, which regulates the power supply by monitoring the external input voltage and controlling the primary-side switching cycle. At the same time, the UCC28880D can adjust the power switch frequency and operating duty cycle to help achieve higher efficiency, reduce switching noise and EMI, and help optimize power supply design for low- and mid-power offline switchers. Additionally, the controller also includes an integrated isolated feedback control loop and can provide a digital interface for real-time control.
The UCC28880D is also coupled with concurrent and soft switch technologies to reduce design complexity, improve system efficiency and reliability, and reduce EMI. Concurrent switching further improves efficiency and reduces standby power, while soft switching helps reduce noise and EMI. Additionally, the UCC28880D features a low-noise sync output, allowing thecontroller to synchronize with an external oscillator, such as an RTC, for additional power savings.
In summary, the UCC28880D is an impressive piece of technology and is ideal for low-power offline switching power supplies, such as consumer electronics and office equipment. Its adaptive digital system, embedded MOSFET driver, and various protections allow for efficient and reliable operation. Coupled with the concurrent and soft switching technologies, the controller helps to reduce design complexity, optimize efficiency, and minimize noise and EMI. The UCC28880D is a great choice for low-power, offline applications.
