The XC9273 series is a group of synchronous-rectification type DC/DC converters with a built-in 47mΩ P-channel MOS driver transistor and 36mΩ N-channel MOS switching transistor, designed to allow the use of ceramic capacitors. The small on-resistances of these two internal driver transistors enable a high efficiency, stable power supply with an output current up to 3.0A. A 0.6V reference voltage source is incorporated, and the output voltage can be set freely by external resistors. Oscillation frequency is set to 1.2MHz or 3.0MHz can be selected for suiting to your particular application. The operation mode is HISAT-COT (*) control, which has an excellent transient response. PWM control or PWM/PFM auto switching control can be selected at the MODE1 pin, and a high-speed response, low ripple, and high efficiency are achieved across the entire load range (from light loads to heavy loads). As for the soft-start function as fast as 0.25ms in typical for quick turn-on. The soft start time can be set as desired by adding an external capacitance to the SS pin. Internal protection circuits include over current protection, short-circuit protection, and thermal shutdown circuits to enable safe use. Short circuit protection or Hiccup mode can be selected at the MODE2 pin. Soft-off function and CL High Speed discharge function discharge the electric charge at the output capacitor CL when putting the IC in a stand-by mode. Soft-off function can be selected at the MODE3 pin.
