This power module generates all the voltages required to power the Class D audio amplifier. The main output voltage is 36V, which provides 200W of continuous power and 540W of peak power. The first stage is a power factor correction boost. The flyback converter provides 12V on the primary side and 12V (300mA) and 3.3V (200mA) on the secondary side. Using a hardware switch and remote input, the converter can enter standby mode: in this state, the 36V output is disabled and 12V, 3.3V are "always on". In this way, the standby power can be reduced to 150mW (115Vac) and 270mW (230Vac). A second digital input switches the main input voltage from 36V to 18V, allowing it to enter a low-current consumption mode when the audio amplifier requires less power.
This envelope tracking power supply reference design helps extend battery life in portable audio applications such as Bluetooth® or Wi-Fi speakers. The low-power buck converter in this design features envelope tracking for audio power amplifiers, maintaining high efficiency over the output voltage range. By adding an audio envelope signal to the FB pin of TI's TPS61178 device, the output voltage can change according to the envelope of the audio signal, thereby dynamically adapting to the power supply of the TPA3128D2 power amplifier and optimizing its power consumption.

This design can be used as a handheld BERT to evaluate the signal integrity and bit error performance of high-speed subsystems.

The design is divided into four main parts:
The TIDA-00771 is a 20A RMS driver for three-phase brushless DC (BLDC) motors in power tools powered by 3-cell Li-ion batteries (voltage range 5V to 12.6V). The design is a compact 45 x 50 mm actuator that enables sensor-based trapezoidal control. The design uses a discrete compact MOSFET-based three-phase inverter that delivers 20A RMS continuous (70A peak for 1 second) winding current without the need for any external cooling devices or heat sinks. The gate driver's slew rate control and charge pump ensure maximum inverter efficiency (>97% at 10.8V DC) from 5V to 12.6V with optimal EMI performance. Cycle-by-cycle overcurrent protection prevents large stall currents in the power stage, and the board can operate in ambient temperatures up to 55°C. The small form factor allows placement of the plate close to the battery pack, the high efficiency allows the battery to last longer, and the 70A peak current capacity delivers high instantaneous peak torque in power tools.
TI reference design TIDA-00947 demonstrates a 10.5mmx14.5mm, 92% efficient low electromagnetic interference (EMI) DC/DC module using the TPS54202, replacing low dropout regulators (LDOs) in most appliance applications. High efficiency eliminates the need for a heat sink, resulting in a smaller, lower cost solution. Higher current capacity enables the addition of more functionality (WiFi, sensors, etc.). High efficiency and low current consumption help achieve stringent energy efficiency ratings.
