DESCRIPTION

· BD5427EFS is a 7W + 7W stereo class-D power amplifier IC designed for space-saving and low heat-generation applications like low-profile TV sets.

· Utilizes Bipolar, CMOS, and DMOS (BCD) process technology to eliminate turn-on resistance and internal loss, achieving 80% efficiency with 8 Ω load.

· Features a compact back-surface heat radiation type power package, eliminating the need for an external radiator up to 14W total output.

FEATURES

· High efficiency of 80% (7W + 7W output with 8 Ω load) and low heat-generation.

· Supports driving a lowest rating load of 6 Ω.

· Reduces pop noise during power on/off and power interruption.

· Implements high-quality audio muting with soft-switching technology.

· Includes built-in protection circuits against high temperatures, VCC shorting, GND shorting, reduced-voltage, and DC voltage application to speakers.

· Master/slave function for synchronization of multiple devices to reduce beat noises.

· Adjustable internal PWM sampling clock frequencies (250kHz to 400kHz) for protective measures against unwanted radio emission to AM radio band.

· Compact back-surface heat radiation type power package (HTSSOP-A44).

APPLICATIONS

· Low-profile TV sets.

· Space-saving and low heat-generation audio systems.
