50mA/200mA Inductor Built-in Step-Down “micro DC/DC” Converters

ETR28009-001a

■

GENERAL DESCRIPTION

The XCL210 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 2.0V to 6.0V enables support for applications

that require an internally fixed output voltage from 1.0V to 4.0V in increments of 0.05V.

With the built-in UVLO (Under Voltage Lock Out) function, the internal P-channel MOS driver transistor is forced OFF when

input voltage becomes UVLO ditect Voltage or lower.
