Additional Details:

The ACT413AUS-T uses a fixed-frequency PWM control scheme to optimize efficiency over a wide load range. Its synchronous rectification minimizes power loss by replacing the traditional Schottky diode with a low RDS(on) MOSFET. This, combined with its low quiescent current, makes it ideal for battery-powered applications where maximizing run-time is critical. The device also includes built-in protection features such as short-circuit protection and thermal shutdown, ensuring the safety and reliability of the system. Active-Semi designs their PMICs with ease-of-use in mind, so the ACT413AUS-T utilizes internal compensation, reducing the number of external components needed and simplifying the design process. The ACT413AUS-T allows engineers to create smaller, more efficient, and more reliable portable devices.
