The UCC35701N is a high-efficiency, low-power synchronous step-down DC-DC converter for a variety of PMIC (Power Management IC) applications. It features a low quiescent current and an adjustable frequency. This DC-DC converter can be applied in a wide range of AC/DC converter, offline switcher and other applications.

The UCC35701N\'s working principle is based on synchronous rectification, which helps to reduce power losses due to lower power consumption, as well as to enhance efficiency and improve thermal performance. In this scheme, both the low-side and the high-side MOSFETs are operated in a synchronous bridge configuration. This allows the UCC35701N to switch at a higher frequency than traditional non-synchronous architectures, meaning that a smaller footprint can be achieved for the DC-DC converter.

The UCC35701N operates from a wide input voltage range from 2.3V to 24V, allowing it to be used in a wide variety of applications. The output voltage can also be adjusted very accurately, down to 0.8V, using an integrated voltage reference. The UCC35701N features a maximum output current of 2A and a switching frequency from 200kHz up to 2MHz, allowing excellent flexibility in terms of performance and design.

The UCC35701N is specifically designed for offline applications, providing reliable operation through a wide range of input voltages, temperatures and output currents. The device is rated for operation at up to 100°C, making it suitable for extreme environments. The device also offers very fast transient response, making it ideal for applications where fast load current transients are common.

The UCC35701N is a versatile DC/DC converter, offering high performance, high efficiency, and a wide operating voltage range. It is suitable for a variety of applications, such as AC/DC converters and offline switchers, and is particularly useful for applications where fast transient response and low power consumption are required. By combining synchronous rectification with a wide range of adjustable parameters, the UCC35701N provides an excellent solution for high efficiency power regulation.

The UCC35701N is available in industry-standard SOIC-8 package, making it an economical and highly reliable solution for many power management applications.
