... Theory of Operation The ISL8036, ISL8036A is a dual 3A or current sharing 6A step-down switching regulator optimized for battery- powered or mobile applications. The regulator operates at 1MHz (ISL8036) or 2.5MHz (ISL8036A) fixed switching frequency under heavy load condition. The two channels are 180° out-of-phase operation. The supply current is typically only 8µ ...

... Duty Cycle The ISL8036, ISL8036A features 100% duty cycle operation to maximize the battery life. When the battery voltage drops to a level that the ISL8036, ISL8036A can no longer maintain the regulation at the output, the regulator completely turns on the P-MOSFET. The maximum drop-out voltage under the 100% duty-cycle ...
