2A Step-Down Micro DC/DC Converter with Integrated Coil
The XCL211/12 series is an ultra small step-down micro 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 operating voltage range is from 2.7V to 6.0V and the output voltage can be set freely from 0.9V to VIN using external resistors.
The XCL211/212 series include 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 once the chip temperature reaches 150°C and re-starts it when the temperature drops to 130°C (TYP.) or less. Available in a USP-11B01 package (3.1mm x 4.7mm x 1.3mm).
