CategoryPower Management - DC2DC
WD1071VA is a synchronous step-down DC-DC converter optimized for high efficiency and compact solution size. The device integrates switches capable of delivering output current up to 1A. At the whole load range, the device operates in quasi fixed frequency constant on time mode with 1.5 MHz switching frequency. In shutdown, the current consumption is reduced to less than 2 μA.
An internal soft start circuit limits the inrush current during startup. Other features like over current protection and thermal shutdown protection are built-in.
The WD1071VA is available in SOT-563 package. Standard product is Pb-free and Halogen-free.
