XCL212 Series

2.0A Inductor Built-in Step-Down “micro DC/DC” Converters

The XCL212series is a synchronous step-down micro DC/DC converter which integrates an inductor and a control IC in one tiny package (3.1mm×4.7mm, h=1.3mm).

An internal coil simplifies the circuit and enables minimization of noise and other operational trouble due to the circuit wiring.

A wide operating voltage range of 2.7V to 6.0V enables support for applications that require an externally set output voltage can be selected. The XCL212 series achieves high efficiency while holding down output ripple across the full range of loads, from light to heavy, enabling the extension of battery operation time.

The series have a high speed soft-start as fast as 1ms in typical for quick turn-on. With the built-in UVLO (Under Voltage Lock Out) function, the internal P-channel driver transistor is forced OFF when input voltage becomes 2.4V or lower. It’s suitable for large-current application due to limit current is configured 4.0A in typical. The integrated CL discharge function which enables the electric charge at the output capacitor CL to be discharged via the internal discharge switch located between the LX and VSS pins. Due to CL discharge function, malfunction on LX is prevented when Stand-by mode.
