Description

      This is the GENERAL DESCRIPTION of XC6367/68 series: 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 are possible using an externally connected transistor, coil, diode and capacitor. Output voltage is selectable in 100mV increments within a range of 1.5V ~ 6.5V (±2.5%). For output voltages outside this range, we recommend FB version, which has a 1.0V internal reference voltage. Using the FB version, the required output voltage can be set-up using 2 external resistors.
      With a 300kHz oscillation 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 XC6367/68 series, D, and F series regulate soft-start time by connecting resistors and capacitors externally.
During stand-by (CE pin "Low"), supply current is reduced to less than 0.5A.
      And these are the FEATURES of XC6367/68 series: Firstly, Input Voltage Range is from 0.9V to 10V. Secondly, Operating Voltage Range is from 2.0V to 10V. Thirdly, Output voltage Range is from 1.5V to 6.5V programmable in 100mv increments (±2.5%). Fourthly, Oscillation Frequency is 300khz, 100khz (±15%) Custom products for 180khz, 500khz. Fifthly, Output Current is More than 200ma (VIN=1.8V, VOUT=3.3V). Sixthly, High Efficiency is 84% (TYP.). Seventhly, Stand-by capability is ISTB=0.5A (MAX.). Eighthly, Selection is Soft-start set-up external Output voltage set-up internal(VOUT) Output voltage set-up external(FB). And at last, Package is SOT-25.
