The ADP1829 is a versatile, dual, interleaved, synchronous PWM buck controller that generates two independent output rails from an input of 3.0 V to 18 V, with power input voltage ranging from 1.0 V to 24 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 point-of-load regulators. The two channels operate 180 out of phase, reducing stress on the input capacitor and allowing smaller, low cost components. The ADP1829 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 ADP1829 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 can also be synchronized to an external clock to achieve switching
