XCL210C181GR-G

XCL210C181GR-G is an 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 2.0V 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. During stand-by, all circuits are shutdown to reduce current consumption to as low as 0.1µA or less. With the built-in UVLO function, the internal P-channel MOS driver transistor is forced OFF when the input voltage becomes UVLO detects voltage or lower. It integrates 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. Application includes wearable devices, smart meters, Bluetooth units, energy harvest devices, backup power supply circuits, portable game consoles, devices with 1 Lithium cell.
