2.2 U703(AT1529F11U)
General Description
The AT1529 high-efficiency, DC/DC buck converter delivers up to 3.2A of output current. The device operates from an input voltage of 2.5V to 6V and
provides an output voltage from 0.8V to VIN, making the AT1529 ideal for on-board post-regulation applications.
The AT1529 operate at a fixed frequency of 1MHz with an efficiency of up to 94%. The high operating frequency minimizes the size of external
components. Internal soft-start control circuitry reduces inrush current. Short-circuit and thermal-overload protections improve design reliability.
The AT1529 are available in a space-saving SOP-8 and TDFN3X3-8 package.

2.3 U602(STA339BWTR)
General Description
The STA339BW is an integrated solution of digital audio processing, digital amplifier control, and FFX-power output stage, thereby creating a high-power
single-chip FFX® solution comprising high-quality, high-efficiency, all digital amplification.
STA339BW is based on FFX (fully flexible amplification) processor, a STMicroelectronics proprietary technology. FFX is the evolution and the enlargement
of the ST ternary technology: the new processor can be configured to work in ternary, binary, binary differential and phase shift PWM modulation schemes.
STA339BW contains the ternary, binary and binary differential implementations, a subset of the full capability of the FFX processor.
