XD9268 Datasheet | Torex Semiconductor

DESCRIPTION The XD9267/XD9268 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 XD9267/XD9268 series has an operating voltage range of 3 V to 36 V, a switching frequency of 2.2 MHz, and the circuit scheme of synchronous rectification to be a highly efficient and stable power supply. An internal reference voltage source of 0.75 V is available, and the output voltage can be set to 1 V to 25 V by external res istors (RFB1 and RFB2). 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. Over-current protection and thermal shutdown are built in as protection function, and it can be used safely even in the case of short circuit. Internal protection circuits include over current protection and thermal shutdown circuits to enable safe use. - APPLICATIONS - Automotive Body Control - Automotive Infotainment - Automotive accessories - Drive recorder - Car-mounted camera - ETC - Industrial Equipment - FEATURES Input Voltage Range Output Voltage Range FB Voltage Oscillation Frequency Output Current Quiescent Current Control Methods Soft-start Time Protection functions Output Capacitor Operating Ambient Temperature Packages Environmentally Friendly : 3.0 ~ 36V (Absolute Max 40V) : 1.0 ~ 25V : 0.75V ± 1.5% : 2.2MHz : 600m A : 13.5μA (XD9268) : PWM control(XD9267) : PWM/PFM Auto(XD9268) : Efficiency 88%@12V→5V,300m A : Adjustable by RC Over Current Protection : (Automatic Recovery) 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 - TYPICAL PERFORMANCE CHARACTERISTICS CIN 2.2μ F Lx EN/SS GN D L...
