Overview
XCL219/XCL220 Series is Discontinued.
XCL219/XCL220 Series ETR28010-003a HiSAT-COT ® Control 1.
0A Inductor Built-in Step-Down “micro DC/DC” Converters ■GENERAL DESCRIPTION ☆Green Operation Compatible The XCL219/XCL220 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 XCL219/XCL220 series uses synchronous rectification at an operating frequency of 3.
0MHz.
The XCL219/XCL220 series uses HiSAT-COT (*) synchronous rectification.
HiSAT-COT+PWM control (XCL219) or HiSAT-COT+automatic PWM/PFM switching control (XCL220) 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=Low, the integrated CL discharge function which enables the electric charge at the output capacitor CL to be discharged via the internal discharge switch located between the LX and VSS 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.
