The UCC2807D-1 is part of a family of highly reliable switch-mode controllers aimed at providing voltage regulation in a wide range of applications. It features a low operating current, low power dissipation, and a wide input voltage range. It is designed to be used as a direct source-side or sink-side DC-DC switching controller for power conversion. It is also suitable for various step-down and/or step-up automatic voltage/current-fed paralleling applications.The UCC2807D-1 family has been designed to provide good performance in a wide range of applications, including DC-DC buck regulators, boost regulators, flyback, buck-boost and similar converters, low voltage automotive applications and others.The UCC2807D-1 features two high-current MOSFET drivers, one for the high side, and one for the low side, capable of sinking or sourcing up to 1.3A. It also has dual low power dissipation for efficient gate drive so the device does not generate a lot of heat. It also features a built-in high-efficiency limiting circuit and soft-start for improving system performance.The UCC2807D-1\'s basic working principle is simple. It takes a regulated voltage from the output of a power supply and senses the current level on the inductor. It then continuously adjusts the duty cycle of the control signal to the MOSFET drivers so that no more than a predetermined peak current flows through the inductor. The duty cycle is adjusted to ensure that the load voltage is regulated at the required level.The UCC2807D-1 is used in a variety of applications, including DC-DC buck regulators, boost regulators, flyback, buck-boost and similar converters, low voltage automotive applications and others. It is available in several different packages, and can be used in either single- or double-ended configurations. It is ideal for applications where high efficiency and fast transient response are required.The UCC2807D-1 can be used for stand-alone direct source or sink-side regulation, with the ability to adjust the output current and voltage, as well as sense the current from the power supply. It is designed to integrate seamlessly with external digital and analog components, providing closed-loop regulation and fast transient response. It can also run synchronous or asynchronous bit-bang sequencing, allowing it to be easily adapted for various applications.Overall, the UCC2807D-1 is a powerful switch-mode controller for providing voltage regulation in a wide range of applications. It offers a wide input voltage range, low power dissipation, and a built-in high-efficiency limiting circuit and soft-start. It is able to precisely regulate the output voltage, while providing a fast transient response and the ability to integrate seamlessly with external components. With all of these features, and its designed-in flexibility, the UCC2807D-1 is an ideal choice for power conversion in a variety of applications.
