supply IC. The device includes four synchronous buck
converters, configured to share eight 1A power stages,
each of which is powered from independent 2.25V to
5.5V inputs. n Applications General Purpose Multichannel Power Supplies:
Automotive, Industrial, Distributed Power Systems n The DC/DCs are assigned to one of eight power configurations via pin programmable C1-C3 pins. The common
buck switching frequency may be programmed with an
external resistor, synchronized to an external oscillator, …
