FR9886, Synchronous Step-Down DC/DC Converter, 4.5V to 23V Input, 2.5A Output, SOP-8

The FR9886 is a high-efficiency, synchronous step-down DC/DC converter capable of handling an input voltage range of 4.5V to 23V, delivering up to 2.5A continuous load current. Designed for a variety of applications, it operates at a fixed frequency of 340kHz to achieve optimal performance in compact power supply designs.

The device includes cycle-by-cycle current limiting, under-voltage lockout (UVLO), and output overvoltage protection, along with thermal shutdown, to ensure the utmost reliability in high-power applications. The FR9886 offers adjustable soft-start to prevent high inrush currents during power-up and has a low shutdown current of less than 1µA. Packaged in a thermally efficient SOP-8 or SOP-8 Exposed Pad, it is ideal for low-profile applications where thermal management is key.
