The ISL78322 is a high-efficiency, dual synchronous step-down DC/DC
regulator that can deliver up to 2A/1.
7A continuous output current per channel.
The channels are 180° out-ofphase for input RMS current and EMI reduction.
The supply voltage range of 2.
8V to 5.
5V allows for the use of a single Li+ cell, three NiMH cells or a regulated 5V input.
The current mode control architecture enables very low duty cycle operation at high frequency with fast transient response and excellent loop stability.
The ISL78322 operates at 2.
25MHz switching frequency, which allows for the use...
