■GENERAL DESCRIPTION
☆GreenOperationCompatible
The XCL213/XCL214 series is a synchronous step-down micro DC/DC converter which integrates an inductor and a control
IC in one tiny package (2.5mm×3.2mm, h=1.0mm). 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 5.5V enables support for
applications that require an internally fixed output voltage (0.8V to 3.6V). The XCL213/XCL214 series uses synchronous
rectification at an operating frequency of 3.0MHz. The XCL213/XCL214 series uses HiSAT-COT (*) synchronous rectification.
HiSAT-COT+PWM control (XCL213) or HiSAT-COT+automatic PWM/PFM switching control (XCL214) can be selected.
The series have a high speed soft-start as fast as 0.3ms 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 2.0V or lower. When
CE=”L”, 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. The power consumption will be less than 1.0μA.
