MILPITAS, CA - February 25, 2016 - Linear Technology Corporation announces the LT8641, a 3.5A, 65V input capable synchronous step-down switching regulator. A unique Silent Switcher® architecture, combined with spread spectrum frequency modulation, reduces EMI/EMC emissions by more than 25dB even with switching frequencies in excess of 2MHz, enabling it to easily pass the automotive CISPR25 class 5 peak and average limits. Synchronous rectification delivers efficiency as high as 94% with a switching frequency of 2MHz. Its 3V to 65V input voltage range makes it ideal for single or dual cell automotive/transportation and industrial applications.
