TOREX XCL232D311KR-G

The XCL232 series is a synchronous step-down micro DC/DC converter which integrates an inductor and a control IC in one tiny package. It uses an ultra-low current consumption circuit and PFM control. The control IC and coil are integrated to achieve miniaturization, and a space-saving power supply can be configured simply by adding two external capacitors. In addition, the ultra-low current consumption circuit and PFM control method realize high efficiency with a light load. A operating voltage range of 1.8V to 6.0V enables support for applications that require an internally fixed output voltage from 0.5V to 3.6V. It has a built-in UVLO function, the internal P-channel driver FET and N-channel driver FET are turned OFF when input voltage is below to the UVLO detection voltage. The D type integrate CL discharge function which enables the electric charge at the output capacitor CL to be discharged via the internal discharge switch located between the VOUT and GND. When the devices enter stand-by mode, output voltage quickly returns to the GND level as a result of this function.
