XCL219B333FR-G

XCL219B333FR-G is a XCL219 series HiSAT-COT® Control 1.0A inductor built-in step-down “micro DC/DC” converter. An internal coil simplifies the circuit and enables the 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 of 0.8V to 3.6V. It uses synchronous rectification at an operating frequency of 3.0MHz. It has 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 the input voltage becomes 2.0V or lower. When CE=Low, the integrated CL discharge function 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 application includes notebook PC, tablet PC, SSD(solid state drive), mobile phone, digital still camera, portable game machine.
