XC6367_68x Input Voltage Range: 0.9~10.0V x Output Voltage Range: 1.5~6.5V(±2.5%) x Oscillator Frequency: 300kHz(±15%) x PWM/PFM Switching Control (XC6368) x High Efficiency: 84% (typ.) x SOT-25 Package s General Description 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 (VOUT) is programmable in 0.1V steps from 1.5V to 6.5V (±2.5% accuracy). Further, with 1.0V of standard voltage supply internal, and using externally connected components, output voltage (FB) can be set up at will. With a 300kHz switching frequency, the size of the external components can be reduced. Control switches from PWM to PFM……
