AC/DC and DC/DC Conversion > DC/DC SMPS - Single Output XRP6658EVB: 3.3V @ 1A, 3.3 ~ 5.5V in Manufacturer: MaxLinear, Inc.

The XRP6658 is a synchronous current mode PWM step down (buck) converter capable of delivering up to 1 Amp of current and optimized for portable battery-operated operations.

Audio Amplifiers TAS6422Q1EVM: 75W x 2 @ 4Ω, Digital Input, w/I2C Diagnostics, Class-D, 2.1Mhz Manufacturer: Texas Instruments

The TAS6422Q1EVM showcases the first true 2.1Mhz 2-Ch Digital Input Class-D Audio Solution for Automotive Infotainment in the market. TAS6422’s 2.1-Mhz switching frequency allows customers to significantly reduce inductor size and cost and optimize total system cost. TAS6422 delivers 25W (10% THD+N) per channel into 4-Ω with a 14.4-V supply.

Audio Amplifiers TPA3156D2EVM: 70W x 2 @ 4Ω, Class-D, Inductor Free Manufacturer: Texas Instruments

The TPA3156D2 has low idle power loss and helps to extend the battery life of Bluetooth/Wireless speakers and other battery-powered audio systems. The high efficiency of the TPA3156D2 device allows it to do 2 × 70 W with external heat sink on a dual layer PCB. This device integrates an efficiency boost mode, which dynamically reduces the current ripple of the external LC filter and the idle current.
