Product Description


2A Step-Down Micro DC/DC Converter with Integrated Coil

Application Notes

The XCL211 is an ultra small (3.1 x 4.7 x 1.3mm) micro step-down DC/DC converter with an integrated coil that achieves a level of miniaturization and profile reduction that is one of the smallest in class for a load current of 2A.

With the integrated Inductor, this new series is designed to minimise EMC emissions and radiated noise, whilst maximising efficiency.

The XCL211 includes a 1ms (typ.) high speed soft-start function for quick turn-on, a chip enable pin to turn the IC on and off and a CL discharge function to quickly discharge the output capacitor when the IC is turned off. A thermal shutdown circuit is also built in which shuts down the IC when the chip’s temperature reaches 150°C and re-starts it when the temperature drops to 130°C (TYP.) or less.
