ADZS-AD2428MINI is a low-cost, mini break-out board which can interface with EV-SOMCRR-EZKIT (via a 100-pin connector) or any custom board (via a 32 pin 0.1" header). It supports main and subordinate node capability as well as bus and local power configurations. An Automotive Audio Bus (A2B®) system consists of a single main node and at least one subordinate node, where the transceiver at the host controller is the main node. The main transceiver generates clock, synchronization, and framing for all subordinate nodes and is programmable over a control bus (I2C) for configuration and readback. An extension of this control bus is embedded in the A2B data stream, which enables the host to directly access subordinate transceiver registers and any I2C-connected peripherals on subordinate nodes. Transceivers can connect directly to PDM microphones and to numerous peripherals via I2C and a multichannel I2S/TDM interface. Finally, the transceiver also supports an A2B bus powering feature, where the main node supplies voltage and current to the subordinate nodes over the same daisy-chained, twisted pair wire cable as used for the communication link, thus eliminating the need for a power supply on bus-powered subordinate nodes. Due to the numerous configurations that are possible for a given A2B system, there are several evaluation platforms that can be used in combination to verify system operation, as summarized in the table below.

The LT8620 is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator that accepts a wide input voltage range up to 65V, and consumes only 2.5?A of quiescent current. Top and bottom power switches are included with all necessary circuitry to minimize the need for external components. Low ripple Burst Mode operation enables high efficiency down to very low output currents while keeping the output ripple below 10mVP-P. A SYNC pin allows synchronization to an external clock. Internal compensation with peak current mode topology allows the use of small inductors and results in fast transient response and good loop stability. The EN/UV pin has an accurate 1V threshold and can be used to program VIN undervoltage lockout or to shut down the LT8620 reducing the input supply current to 1?A. A capacitor on the TR/SS pin programs the output voltage ramp rate during start-up. The PG flag signals when VOUT is within ?9% of the programmed output voltage as well as fault conditions.
