Product overview
Description
The STEVAL-3603BC1 evaluation board demonstrates a smart converter design, able to deliver up to 3 A output current from a 3.3 V to 36 V input, with a 5.0 V output voltage. The board features the DCP3603 miniaturized synchronous step-down converter, which implements enhanced peak current control and advanced design circuitry to minimize quiescent current.
The board demonstrates how highly efficient conversion can be achieved with just DCP3603, an inductor, two small capacitors, and two resistors. The board highlights key application benefits made possible by DCP3603, including high efficiency and small PCB size, and is ideal for power conversion solutions in major appliances, smart metering, industrial 24 V bus conversion, and general-purpose wide Vin power supplies. The device used on this board is supplied in the thin SOT23-6L package.
