The FR9801S6CTR is a synchronous step-down DC/DC converter designed by Fitipower Integrated. It operates within a wide input voltage range of 4.5V to 21V and can deliver up to 2A of continuous load current. This converter features a fixed switching frequency of 600KHz, contributing to its fast transient response.
Key features include high efficiency up to 94%, low RDS(ON) integrated power MOSFETs, and internal compensation to simplify design. Fault protection mechanisms such as cycle-by-cycle current limit, UVLO, output overvoltage protection, and thermal shutdown are integrated. The adjustable soft-start function helps prevent inrush current during turn-on.
The FR9801S6CTR is available in a compact SOT-23-6 package, suitable for surface mount applications. Its design is well-suited for applications like Set-Top-Boxes (STB), LCD displays, TVs, distributed power systems, and networking equipment such as XDSL modems.
