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 condenser. Output voltage 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.
