TI Designs TIDA-00449 is a ready-to-use and tested hardware platform for monitoring, balancing and protecting power tool 10-cell series battery packs. Power tools increasingly use high power density battery packs based on lithium-ion or lithium iron phosphate cells, which require explosion protection against incorrect charging or discharging. TIDA-00449 also meets the thermal requirements for power tool battery packs when discharged at sustained high currents.
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 reference design is a 12Gbps low-cost bit error tester (BERT) that generates and checks up to 8 channels of pseudo-random binary sequences (PRBS). This proven design provides a convenient way to generate multi-lane high-speed serial bit streams up to 12Gbps and inspect the incoming serial bit stream for bit errors. This design can be used as a handheld BERT to evaluate the signal integrity and bit error performance of high-speed subsystems.
