This design uses the highly flexible PCM5242 differential output DAC to convert the extremely high performance analog input TPA3251D2 Class D amplifier into a digital input system with audio processing capabilities. The full performance of the TPA3251D2 amplifier can now be achieved through a variety of digital input sources. The PCM5242 DAC's analog differential output and high SNR are a perfect match for the TPA3251D2 amplifier's full differential analog input, resulting in excellent noise performance and very low distortion. Through the miniDSP on the PCM5242, audio processing and filtering functions can be added to further enhance the audio performance in the end device.

The MAX17559 is a dual-output, synchronous step-down controller that drives nMOSFETs. The device uses a constant- frequency, peak-current-mode architecture. The two outputs can be configured as independent voltage rails. Input capacitor size is minimized by running the two outputs 180° out of phase. The IC supports current sensing using either an external current-sense resistor for accuracy or an inductor DCR for improved system efficiency. Current foldback or latch-off limits MOSFET power dissipation under short-circuit conditions. The IC provides independent adjustable soft-starts/stops for each output and can start up monotonically into a pre-biased output. The IC can be configured in either PWM or DCM modes of operation, depending on whether constant-frequency operation or light-load efficiency is desired. The IC operates over the -40°C to +125°C temperature range and is available in a lead(Pb)-free, 7mm x 7mm, 32-pin TQFP, package.

The TIDA-01494 reference design is a compact, high-efficiency, 24V DC, 480W nominal, 720W peak output reference design for industrial AC/DC power supplies. The circuit includes a front-end continuous conduction mode (CCM) power factor correction (PFC) circuit, followed by a powerful LLC stage with synchronous rectification. The design ensures an efficiency greater than 93.5% over a wide load range, allowing the system to operate without forced cooling. The UCC256301-based LLC stage utilizes the ZCS avoidance feature in the UC256301 to achieve peak output power, minimizing the PFC bulk capacitor to meet holdup requirements while enabling the system to handle short circuit and overcurrent conditions. The UCC24612-2-based synchronous rectifier helps minimize losses in the output rectifier, while its advanced proportional gate driver and dead-time optimization help avoid breakdown and minimize losses.
