chronous Step-Down Silent Switcher Delivers 94% Efficiency at 2 MHz
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. […]
Linear regulators target high input-to-output voltage, high output current apps
Linear Technology Corporation announces the LT3089, a rugged 800mA wide input voltage range linear regulator with key usability, monitoring and protection features. The device has an extended safe operating area (SOA) compared to existing regulators, making it ideal for high input-to-output voltage and high output current applications where older regulators limit the output. The LT3089 […]
