With compact dimensions and an input-voltage range from 6 to 75V, STMicroelectronics’ L3751 synchronous buck controller serves different applications from industrial equipment to battery-powered light electric vehicles. The 3.5 x 4.5mm controller is also suited to use in telecom and networking equipment that features commonly used 24 and 48V buses. With a minimum on-time duration…

STMicroelectronics’ TDA7901 automotive amplifier integrates a buck controller for class-G power switching and supports high-definition audio — a market-unique combination for ideal listening and high efficiency. In class-G operation, the TDA7901 buck controller automatically optimizes the voltage supplied to the bridge-tied load (BTL) power-stage, depending on the audio-signal level. The resulting smooth, analog sound comes with…
