Inductor Built-in Step-up “micro DC/DC” Converter (micro DC/DC)

■

GENERAL DESCRIPTION

The XCL102/XCL103 series is a synchronous step-up micro DC/DC converter which integrates an inductor and a control IC

in one tiny package (2.0mm×2.5mm, h=1.0mm). A stable step-up power supply is configured using only two capacitors connected

externally. 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 0.9V to 6.0V enables support for applications that require an internally fixed output

voltage (2.2V to 5.5V). PWM control (XCL102) or automatic PWM/PFM switching control (XCL103) can be selected.
