Product Details

Demonstration circuit DC1180 is a dual output regulator consisting of two identical constant frequency step-down converters, based on the LTC3407A monolithic dual synchronous buck regulator in the 3 × 3 DFN-10 package. The LTC3407A is similar to the LTC3407 but has a lower ripple Burst Mode operation and includes an optional external soft-start. The DC1180 has an input voltage range of 2.5V to 5.5V, and either output is capable of delivering up to 600mA of output current. In Burst Mode® operation, the DC supply current is typically only 25 µA (per channel) at no load, and less than 1 µA in shutdown. The DC1180 is a very efficient circuit: up to 96% for either circuit.
