Universal input 3.3V, 12V, 36V, 200W continuous PSU reference design for Class D amplifiers

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.

Monitoring, balancing and protection of 10-cell battery pack

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.

Overcurrent monitor operates up to 26V

Using a current-sense amplifier, a high-side MOSFET driver, and a latching voltage monitor a circuit can be easily constructed that protects from overcurrent conditions and operates at voltages as high as 26V.

USB Type-C Audio Adapter Accessory Mode Reference Design

The USB Type-C™ Audio Adapter Accessory Mode Reference Design provides a solution for transmitting analog audio over the USB Type-C interface. This reference design demonstrates how to use the USB Type-C standard audio adapter accessory mode to transmit analog audio to system peripherals while still transmitting USB data through the same USB Type-C connector.
