XCL237/XCL238Series

ETR28025-001

HiSAT-COT _®Control 1.5A Inductor Built-in Step-Down “micro DC/DC” Converters

☆Green Operation Compatible

■GENERAL DESCRIPTION

The XCL237/XCL238 series is a synchronous step-down micro DC/DC converter which integrates an inductor and a control

IC in one tiny package (3.2mm x 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.

The Output voltage is internally set in a range from 0.8V to 3.6V increments of 0.05V.

HiSAT-COT is a proprietary high-speed transient response technology for DC/DC converter which was minimized output

voltage during load fluctuations. It is Ideal for the applications with large instantaneous load fluctuations such as FPGAs and

equipment that requires stable output voltage.

^(*)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.
