Overview

Product Details

Demonstration circuit 3220A is a 18V, 8A synchronous step-down Silent Switcher® 3 with ultralow noise, high efficiency and power density featuring the LT8625SP-1. The input voltage range of DC3220A is 2.7V to 18V. The default demo board setting is 1V at 8A maximum DC output current. The LT8625SP-1 is a compact, ultralow noise, ultralow emission, high efficiency and high speed synchronous monolithic step-down switching regulator. The uniquely designed combination of the ultralow noise reference and the third-generation Silent Switcher architecture enables the LT8625SP-1 to achieve both high efficiency and excellent wideband noise performance. Minimum on-time of 15ns allows high VIN to low VOUT conversion at high frequencies.
