Three phase step-down DC/DC controller targets high current rails. Linear Technology has launched the LTC3829; a three-phase single output high efficiency (up to 95%) synchronous step-down DC/DC controller with PolyPhase operation, differential output voltage sensing and integrated phased-lock loop (PLL) clock synchronisation. Up to six phases can be paralleled and clocked out of phase to minimise input and output filtering requirements for high current applications (up to 150A)....
Active load pull solutions
Mesuro has released frequency extensions to its MB series of active load pull solutions. Additionally, the company shared the results of its work with industry leaders to design harmonically tuned, near theoretically-efficient power amplifiers (PAs). These meet the needs of commercial and military applications for obtaining highly efficient, high power PAs. These designs will extend battery life, lower operating temperatures, improve reliability and offer smaller overall...
