BD5413EFV is a 5W + 5W stereo Class-D power amplifier specifically developed for low power consumption and low heat generation applications like powered speakers. BD5413EFV employs the state-of-the-art BCD (Bipolar, CMOS and DMOS) process technology to eliminate a turn-on resistance in the output power stage and an internal loss due to a wiring resistance as much as possible, achieving a high performance of 80% (4W + 4W output with a load resistance of 8Ω). In addition, BD5413EFV employs a compact power package which dissipates heat via the rear to achieve low power consumption and low heat generation so that the need for connecting an external heat radiator can be eliminated up to a total output of 12.8W. This product meets the needs for compact, thin sound generation systems and powerful, high-quality sound reproduction.
The BD5413EFV is a Class‑D stereo power amplifier designed for low power consumption and low heat generation, suitable for compact powered‑speaker applications. It delivers up to 4 W per channel (8 W total) with 80 % efficiency and includes features such as soft‑mute, error pin, and built‑in protection circuits.
The datasheet details absolute maximum ratings, operating conditions, electrical characteristics, characteristic curves, pin‑assignment diagrams, package dimensions, and ordering part numbers, offering all necessary information for circuit design and product integration.
