Analog Devices LT8692S | Demoboard EVAL-LT8692S-AZ

Description

Demonstration circuit EVAL-LT8692S-AZ is an ultracompact 4 rail power supply featuring the LT®8692S,a 42V quad monolithic synchronous step-down Silent Switcher®. The demo circuit is designed for 5V, 3.3V,1.8V, and 1.2V outputs from a nominal 12V input. The 3.3V, 1.8V and 1.2V converters are powered from the high voltage buck regulator with 5V output, which is powered from a wide range of 6.2V to 42V input. The current capability is 2A for the channel 1, and 1A for the low voltage channels.
