TOREX SEMICONDUCTOR XC9257

the XC9257 series is PWM control, the XC9258 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). 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.

GENERAL DESCRIPTION

☆GreenOperation-compatible The XC9257/XC9258 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. As for operation mode HiSAT-COT (*) control excellent in transient response, 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. Two types of package SOT-25, USP-6C are available. (*) HiSAT-COT is an original Torex term for High Speed Transient Response.
