XCL223/XCL224 Series

ETR28012_005

HiSAT-COT_®0.7A Inductor Built-in Step-Down “micro DC/DC” Converters

☆Green Operation Compatible

■GENERAL DESCRIPTION

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 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. When CE=”L”, the integrated C_Ldischarge

function which enables the electric charge at the output capacitor C_Lto be discharged via the internal discharge switch located

between the L_Xand PGND pins. The power consumption will be less than 1.0μA.

^(*)HiSAT-COT is a proprietary high-speed transient response technology for DC/DC converter which was developed by Torex. It is Ideal for the

LSI's that require high precision and high stability power supply voltage.
