DC2009A, Demonstration Board using LT3791-1, 60V four-switch synchronous buck-boost controller

DC2009A, Demonstration Board is a 60V four-switch synchronous buck-boost controller that demonstrates the high power capability of the LT3791-1. The output is 24V and the maximum output current is 5A. The switching frequency is 200kHz and efficiency is as high as 98% for a 24V input. The operating input voltage range of DC2009A is from 12V to 57V. The output voltage, EN/UVLO, and OVLO are all programmed by resistor dividers. The demo circuit features MOSFETs that compliment the 5V gate drive of the LT3791-1 to achieve high efficiency
