XCL222B121ER-G

XCL222B121ER-G is a XCL222 series HiSAT-COT ® Control 0.5A inductor built-in step-down “micro DC/DC” converter which integrates an inductor and a control IC. 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). This uses synchronous rectification at an operating frequency of 1.2MHz. This HiSAT-COT synchronous rectification HiSATCOT+automatic PWM/PFM switching control. This 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 input voltage becomes 2.0V or lower. Applications include wearable device, Bluetooth module, SSD, mobile phone, digital still camera, portable game devices.
