XCL210 Series ETR28009-005a 50mA/200mA Inductor Built-in Step-Down “micro DC/DC” Converters ☆Green Operation Compatible ■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. During stand-by, all circuits are shutdown to reduce current consumption to as low as 0.1μA or less. 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 detect Voltage or lower. The XCL210 integrate 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. When the devices enter stand-by mode, output voltage quickly returns to the VSS level as a result of this function. ■APPLICATIONS ● Wearable Devices ● Smart meters ● Bluetooth units ● Energy Harvest devices ● Backup power supply circuits ● Portable game consoles ● Devices with 1 Lithium cell ■FEATURES Input Voltage : 2.0V ~ 6.0V Output Voltage : 1.0V ~ 4.0V (±2.0%) Control Methods : PFM control Output Current : 200mA (Type A/C) 50mA (Type B/D) Supply Current : 0.5μA High Efficiency Function : 93% (VIN=3.6V,VOUT=3.0V/100μA) : UVLO Short Circuit Protection Capacitor CL Discharge(Type C/D) : Low ESR Ceramic Capacitor Operating Ambient Temperature : -40℃ ~ 85℃ Packages : CL-2025-02 Environmentally Friendly : EU RoHS Compliant, Pb Free ■TYPICAL APPLICATION CIRCUIT 7 CL 50mA 22μ F 1 Lx 2 GND VIN 6 NC 5 3 VOUT CE 4 8 VIN CIN 10μ F ■ TYPICAL PERFORMANCE CHARACTERISTICS XCL210B301GR-G (VOUT=3.0V) 100 80 Efficiency : EFFI [%] 60 40 20 0 0.01 VIN=3.6V VIN=4.2V 0.1 1 10 100 Output Current : IOUT [mA] 1/25 XCL210 Series ■BLOCK DIAGRAM XCL210 Series, Type A/B L2 VOUT CE VIN Inductor Short Protection R1 CFB PFM Comparator Current Sense R2 Vref CE Controller Logic PFM Controller VDD UVLO VIN Start Up Controller VDD Synch Buffer Drive * XCL210A and B type do not have CL Discharge function. * Diodes inside the circuits are ESD protection diodes and parasitic diodes.
