DC2535A is a 42V, dual channel, 2A synchronous step-down regulator featuring the LT®8653S. The LT8653S is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator which features the second generation Silent Switcher® technology that minimizes EMI and reduces PCB layout sensitivity.
The DC2535A demonstration circuit is a 42V, dual-channel, 2A synchronous step-down regulator designed to evaluate the LT8653S IC. The board features two outputs: 5V and 3.3V, selectable via jumpers JP3 and JP4, and supports a wide input range from 5.5V to 42V. It utilizes Analog Devices' Silent Switcher technology to minimize EMI and reduce PCB layout sensitivity.
