GENERAL DESCRIPTION
☆Green Operation Compatible The XCL223/XCL224 series is a synchronous step-down micro DC/DC converter which integrates an inductor and a control IC in one tiny package (2.25mm×1.5mm, h=0.75mm). 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 2.5V to 5.5V enables support for applications that require an internally fixed output voltage (0.8V to 3.6V). The XCL223/XCL224 series uses synchronous rectification at an operating frequency of 3.0MHz. The XCL223/XCL224 series uses HiSAT-COT synchronous rectification. HiSAT-COT+PWM control (XCL223) or HiSAT-COT+automatic PWM/PFM switching control (XCL224) can be selected. The maximum load current can be selected either 400mA or 700mA. The series have a high speed soft-start as fast as 0.3ms in typical for quick turn-on. With the built-in UVLO function, the internal P-channel driver transistor is forced OFF when input voltage becomes 2.0V or lower.
