Demonstration circuit 1435 is a dual output regulator consisting of two constant-frequency step-down converters, based on the LTC3615 dual channel monolithic synchronous buck regulator in the 4mm × 4mm QFN-24 package. The DC1435 has an input voltage range of 2.25V to 5.5V, with each regulator capable of delivering up to 3A of output current. The DC1435 can operate in Burst Mode^®, pulse-skip or forced continuous mode. In shutdown, the DC1435 requires less than 100 uA total. The DC1435 is a very efficient circuit: over 90% for either circuit. The LTC3615 comes in a 24 Pin QFN or leaded package, which each having an exposed pad on the bottom-side of the IC for better thermal performance.
