XC9260/XC9261Series ETR05042-005 HiSAT-COT ® Control, 1.5A Synchronous Step-Down DC/DC Converters ☆GreenOperation-compatible ■GENERAL DESCRIPTION The XC9260/XC9261 series is a group of synchronous-rectification type DC/DC converters with a built-in P-channel MOS driver transistor and N-channel MOS switching transistor, designed to allow the use of ceramic capacitors. Output voltage is internally set in a range from 0.8V to 3.6V (accuracy: ±2.0%) increments of 0.05V. The device provides a high efficiency, stable power supply with an output current of 1.5A to be configured using only a coil and two capacitors connected externally. Oscillation frequency is set to 1.2MHz or 3.0MHz can be selected for suiting to your particular application. As for operation mode HiSAT-COT (*) control excellent in transient response, the XC9260 series is PWM control, the XC9261 series is automatic PWM/PFM switching control, allowing fast response, low ripple and high efficiency over the full range of loads (from light load to heavy load). During stand-by, all circuits are shutdown to reduce current consumption to as low as 1.0μA or less. As for the soft-start function as fast as 0.3ms in typical for quick turn-on. With the built-in UVLO (Under Voltage Lock Out) function, the internal P-channel MOS driver transistor is forced OFF when input voltage becomes 2.00V or lower. The B types integrate CL High Speed discharge function which enables the electric charge at the output capacitor CL to be discharged via the internal discharge. Two types of package SOT-89-5, USP-6C are available. (*) HiSAT-COT is DC/DC converter with proprietary high-speed transient response technology developed uniquely by Torex, ideal for LSI that require high precision and high stability power supply voltage. ■FEATURES ■APPLICATIONS ●Communication equipment / Communication Module (Bluetooth/Wi-Fi/GPS） ●MCU/FPGA/ASIC for power supplies (POL) ●Smart phones / Mobile phones ●DSC/Camcorder Input Voltage Range Output Voltage Range Quiescent Current Output Current Oscillation Frequency : : : : : Efficiency : Control Methods : : : : : : : : : : : : : : Protection Circuits Functions Capacitor Operating Ambient Temperature Packages Environmentally Friendly 2.7V～5.5V 0.8V～3.6V (±2.0%) 25μA (fOSC=3.0MHz) 1.5A 1.2MHz, 3.0MHz 90% (VIN=3.7V, VOUT=1.8V, IOUT=200mA) HiSAT-COT Control 100% Duty Cycle PWM Control (XC9260) PWM/PFM Auto (XC9261) Thermal Shutdown Current Limit (Pendent character) Short Circuit Protection (Type B) Soft-Start UVLO CL High Speed Discharge (Type B) Ceramic Capacitor - 40℃ ～ + 105℃ SOT-89-5, USP-6C EU RoHS Compliant, Pb Free ■TYPICAL APPLICATION CIRCUIT ■TYPICAL PERFORMANCE CHARACTERISTICS XC9260A18D / XC9261A18D L = LQM2MPN1R0MGH(1.0μH) CIN=10μF(GRM155R61A106M) CL=10μF(GRM155R61A106M) VIN Lx CE VOUT CE PGND CIN 100 VOUT 1.5A AGND CL 90 Efficiency: EFFI (%) L VIN 80 70 60 XC9261 VIN = 5.0V VIN = 3.7V 50 XC9260 40 30 VIN = 5.0V VIN = 3.7V 20 10 0 0.1 1 10 100 1000 10000 Output Current: IOUT (mA) 1/25 XC9260/XC9261 Series is Not Recommended for New Designs.
