XCL221/XCL222Series

ETR28008-002a

HiSAT-COT _®Control 0.5A Inductor Built-in Step-Down “micro DC/DC” Converters

☆Green Operation Compatible

■GENERAL DESCRIPTION

The XCL221/XCL222 series is a synchronous step-down micro DC/DC converter which integrates an inductor and a

control IC in one tiny package (2.0mm×2.5mm, 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 2.5V to 5.5V enables support for applications that require an internally fixed output

voltage (0.8V to 3.6V). The XCL221/XCL222 series uses synchronous rectification at an operating frequency of 1.2MHz.

The XCL221/XCL222 series uses HiSAT-COT ^(*)synchronous rectification. HiSAT-COT+PWM control (XCL221) or HiSAT-

COT+automatic PWM/PFM switching control (XCL222) 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 UVLOfunction, the

internal P-channel driver transistor is forced OFF when input voltage becomes 2.0V or lower. When CE=Low, 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.
