Application field

The CYPD2122-20FNXIT is designed to provide intermediary control of power delivery in various power-related applications, such as Power over Ethernet. PoE powers connected devices such as computers, cameras, VoIP phones, and WiFi access points. These connected devices require power in order to operate, and the CYPD2122-20FNXIT assists in delivering this power. The CYPD2122-20FNXIT is also suitable for applications such as automotive battery charging and battery pack assembly.

Working Principle

The CYPD2122-20FNXIT is used to control and monitor the power delivery from an application-specific source to the load. It integrates two separate 200 mV power-rail regulators, two separate PMOS-assisted power switches, and an energy accumulator. The CYPD2122-20FNXIT provides device-level and local control of both Voltage and Current, and also Power Delivery (PD). The power delivery is also monitored using a 10-bit analog-to-digital converter (ADC). The CYPD2122-20FNXIT provides digital control via a standard SPI interface, which allows for communication with a central control unit. The digital control allows for a wide range of power delivery profiles to be applied. The power delivery is optimized for load requirements, and is done with minimal power loss.

The CYPD2122-20FNXIT is a fully integrated power delivery solution that effectively manages and provides power to the connected devices. It provides a robust and reliable power solution for Power over Ethernet (PoE) and other adaptive power applications. It is an efficient and cost effective solution for these power-intensive applications.
