Applications

* where efficiency is a prime consideration. To further maximize the life of a battery source, each external P-channel MOSFET is turned on continuously in dropout (100% duty cycle). In shutdown, each controller draws a mere 8µA. High constant operating frequency of 550kHz allows the use of small exter
