ISL8025, ISL8025A
Compact Synchronous Buck
Regulators
The ISL8025, ISL8025A are highly efficient, monolithic, synchronous step-down DC/DC converters that can deliver 5A of continuous output current from a 2.
7V to 5.
5V input supply.
The devices use current mode control architecture to deliver a very low duty cycle operation at high frequency with fast transient response and excellent loop stability.
The ISL8025, ISL8025A integrates a very low ON-resistance P-Channel (36mΩ) high-side FET and N-Channel (13mΩ) low-side FET to maximize efficiency and minimize external component count.
The 100% duty-cycle operation allows less than 180mV dropout voltage at 5A output current.
