XC9267 Datasheet | Torex Semiconductor

DESCRIPTION The XC9267 series are 36V operation synchronous step-down DC/DC converter ICs with a built-in P-channel MOS driver transistor and N-channel MOS switching transistor. The XC9267 series has operating voltage range of 3.0V~36.0V and high-efficiency power supply up to an output current of 600m A. Low ESR capacitors such as ceramic capacitors can be used for the load capacitor (CL). A 0.75V reference voltage source is incorporated in the IC, and the output voltage can be set to a value from 1.0V to 25.0V using external resistors (RFB1, RFB2). 1.2MHz or 2.2MHz can be selected for the switching frequency. The soft-start time is internally set to 2.0ms (TYP.), but can be adjusted to set a longer time using an external resistor and capacitor. With the built-in UVLO function, the driver transistor is forced OFF when input voltage bees 2.7V or lower. The output state can be monitored using the power good function. Internal protection circuits include over current protection and thermal shutdown circuits to enable safe use. - APPLICATIONS - Electric Meter - Gas Detector - Various Sensor - Industrial Equipment - Home appliance - FEATURES Input Voltage Range Output Voltage Range FB Voltage Oscillation Frequency Output Current Control Methods Soft-start Time Protection Circuits Output Capacitor Operating Ambient Temperature Packages Environmentally Friendly : 3.0 ~ 36V (Absolute Max 40V) 1.0 ~ 25V : 0.75V±1.5% : 1.2MHz, 2.2MHz : 600m A : PWM control Efficiency88%@12V→5V, 300m A : Adjustable by RC : Over Current Protection : Thermal Shutdown : Ceramic Capacitor : -40℃ ~ 105℃ : SOT-89-5 (Without Power Good) : USP-6C (With Power Good) EU Ro HS pliant, Pb Free - TYPICAL APPLICATION CIRCUIT 2.2μF Lx EN/SS GN D RFB1 RFB2 10μF×2 - TYPICAL CHARACTERISTICS XC9267C75Cxx (VIN=12V, VOUT=5V, f OSC=1.2MHz) Efficiency...
