SKUWD1072
The WD1072 is a synchronous step-down DC-DC converter optimized for high efficiency and compact solution size. The device integrates switches capable of delivering an output current up to 2A. At the whole load range, the device operates in the quasi-fixed frequency constant on time mode with 1.5 MHz switching frequency. In shutdown, the current consumption is less than 2 μA.
An internal soft start circuit limits the inrush current during startup. The WD1071 also has built-in features including over current protection and thermal shutdown protection.
The WD1072 is available in an SOT-563 and a DFN1616 package. Standard products are Pb-free and Halogen-free.
