WD10721 is a synchronous Buck DC-DC converters optimized for high efficiency and compact solution size. The device integrates switches capable of delivering an output current up to 2A. At PWM mode, the device operates in quasi fixed frequency constant on time mode with 2.1 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 WD10721 is available in SOT-563 package. Standard product is Pb-free and Halogen-free.
