DC441A - LTC3411EMS | 2.65V ≤ VIN ≤ 5.5V, VOUT = 1.8V/2.5V/3.3V @ 1.25A

Demonstration circuit 441 is a constant-frequency stepdown converter, using the LTC3411 monolithic synchronous buck regulator. The DC441 has an input voltage range of 2.65V to 5.5V, and is capable of delivering up to 1.25A of output current. See the LTC3411A for input voltages down to 2.5V. The output voltage of the DC441 can be set to 1.8V, 2.5V or 3.3V using the appropriate jumper connection, or it can be set to an adjustable value down to 0.8V, the reference voltage of the LTC3411.
