DC840A - LTC3448EDD Demo Board | Vin=2.5V-5.5V, Vout= 1.2V/1.5V/1.8V @600mA Max
Demonstration circuit DC840 is a step-down converter using the LTC3448 monolithic synchronous buck regulator. The DC840 has an input voltage range of 2.5V to 5.5V, and is capable of delivering up to 600mA of output current. The output voltage of DC840 can be set as low as 0.6V, the reference voltage of the LTC3448. The DC840 is especially made for noise sensitive applications, due to a unique design that allows the LTC3448 to automatically switch in auto mode - from a switching regulator to a linear regulator at low output currents.
