XC9145 Datasheet | Torex Semiconductor

DESCRIPTION XC9145 series are synchronous step-up DC/DC converters with a 200mΩ N-channel driver FET and a 270mΩ synchronous Pchannel switching FET built-in. The ultra-low current consumption of 400n A and PWM/PFM auto-switching control have dramatically improved the efficiency of the output current of 10μA or less, which was difficult to achieve in the past. (89.9%@VIN=2.4V, VOUT=3.3V, IOUT=10μA) XC9145 series can significantly reduce the power consumption of battery-powered devices which consume a large percentage of power when the system is in standby mode. It contributes to keeping battery life longer and reducing battery size smaller. - APPLICATIONS - Low power wireless munication products - Low power Io T module - Battery-powered medical devices / Wearable devices (Health monitoring, Fitness devices) - Remote controls - Primary battery portable systems - Metering devices / Smart meter (Gas / Water / Temperature) - Home Security / Home Automation - Energy Harvest - FEATURES Input Voltage Range Fixed Output Voltage Output Current Oscillation Frequency Quiescent Current Efficiency Control Mode Load transient response Protection function Functions Operating Ambient Temperature Package Environmentally Friendly : 0.65V ~ 5.5V (Operation Start Voltage 1.6V) : 3.0V ~ 5.5V (0.1V increments) : 430m A @VOUT=5.0V, VBAT=3.3V 300m A @VOUT=3.3V, VBAT =1.8V : 1.2MHz : 400n A : 89.9% @VIN=2.4V, VOUT=3.3V, IOUT=10μA 93.2% @VIN=2.4V, VOUT=3.3V, IOUT=100m A : Auto PWM/PFM : 300m V @VOUT=3.3V, VBAT=1.8V, IOUT=1m A→200m A : Current Limit : Soft start Load Disconnection : -40℃ ~ 105℃ : SOT-25 (2.8x2.9x1.3mm) USP-6C (1.8x2.0x0.6mm) WLP-6-05 (1.08x1.28x0.4mm) : EU Ro HS pliant, Pb Free - TYPICAL APPLICATION CIRCUIT - TYPICAL CHARACTERISTICS : : : : : : : : : 1/29 XC9145 Series - BLOCK DIAGRAM Lx RFB1 Ph ase...
