TOREX XC9259B2KC1R-G

The XC9259 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 1.0A to be configured using only a coil and two capacitors connected externally. Oscillation frequency is set to 1.2MHz or 6.0MHz 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 MODE pin, and a high-speed response, low ripple, and high efficiency are achieved across the entire load range (from light loads to heavy loads). 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. The package is the ultra-small 1.2mm×1.4mm×h0.3mm (LGA-8B01).
