The ADP1823 is a versatile dual, interleaved synchronous PWM buck controller that generates two independent output rails from an input of 2.9 V to 20 V. Each controller can be configured to provide output voltages from 0.6 V to 85% of the input voltage and is sized to handle large MOSFETs for pointof-load regulators. The two channels operate 180 out of phase, reducing stress on the input capacitor and allowing smaller, low cost components. The ADP1823 is ideal for a wide range of high power applications, such as DSP and processor core I/O power, and general purpose power in telecommunications, medical imaging, PC, gaming, and industrial applications. The ADP1823 operates at a pin-selectable, fixed switching frequency of either 300 kHz or 600 kHz, minimizing external component size and cost. For noise-sensitive applications, it
