FCDC00052, Reference Design Using ADP1829/ADP1864 PWM Buck Controller. The ADP1864 is a versatile, dual output, interleaved, synchronous PWM buck controller that generates two independent outputs from an input voltage of 2.9V to 20V. Each channel can be configured to provide output voltage from 0.6V to 85% of the input voltage. The two channels operate 180 out of phase, which reduces the current stress on the input capacitor and allows the use of a smaller and lower cost input capacitor
