GENERAL DESCRIPTION

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

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
