The XC6367/68 series are multi-functional step-up DC/DC converter controllers with built-in high speed, low ON resistance drivers.
Large output currents of XC6367/68 are possible using an externally connected transistor, coil, diode and condenser.
Output voltage of XC6367/68 is selectable in 0.1 steps within a 1.5V ~ 6.5V range (±2.5%). For output voltages outside this range, we recommend this FB version, which has a 1.0V internal reference voltage. Using this version,the required output voltage can be set-up using 2 external resistors.With a 300kHz switching frequency, the size of the external components can be reduced.
Control switches from PWM to PFM during light loads with the XC6368 (PWM/PFM switchable) and the series is highly efficient from light loads to large output currents.Soft start time of XC6367/68A, B, and C series is internally set to 10msec and XC6367/68C, D, and F series regulate soft start time by connecting resistors and capacitors exteranally. During stand-by time (CE pin "Low"), current consumption is reduced to less than 0.5A.
