SG6902 is a controller designed for power supplies that consist of boost PFC and flyback PWM. It requires few external components to achieve green-mode operation and versatile protections and compensations. The proprietary interleave switching synchronizes the PFC and PWM stages and reduces switching noise. At light loads, PFC stage is turned off to save power and the PWM switching frequency increases.

The TAS5112A is a high-performance integrated stereo digital amplifier power stage designed to drive 6-Ω speakers at up to 50 W per channel. The device incorporates TI’s PurePath Digital� technology and is used with a digital audio PWM processor (TAS50XX) and a simple passive demodulation filter to deliver high-quality, high-efficiency, true-digital audio amplification. The efficiency of this digital amplifier is typically 90%, reducing the size of both the power supplies and heatsinks needed. Overcurrent protection, overtemperature protection, and undervoltage protection are built into the TAS5112A, safeguarding the device and speakers against fault conditions that could damage the system.
