The Fitipower Integrated FR9854SP is a synchronous step-down DC/DC converter designed for efficient power management. It operates with an input voltage range of 4.5V to 18V and can deliver a continuous load current of up to 4A.
This converter utilizes a fast constant on-time control technique (FCOT) for rapid transient response and stability with various output capacitors. It includes integrated power MOSFETs with low RDS(ON) for improved efficiency. The FR9854SP also features power-saving modes for light load conditions to reduce power loss.
Fault protection mechanisms are built-in, including cycle-by-cycle current limit, undervoltage lockout (UVLO), short circuit protection, and thermal shutdown with auto-recovery. A soft-start function prevents inrush current during turn-on. The FR9854SP is available in SOP-8 (exposed pad) and TQFN-16 (3mm x 3mm) packages, both offering good thermal performance.
Key electrical specifications include a reference voltage of 0.765V for the FR9854SP variant and a maximum output voltage of 8V. The switching frequency is pseudo-fixed at 630kHz. This component is suitable for applications requiring stable and efficient power conversion.
