The AP3428AKTTR-G1 from Diodes Incorporated is a 1A step-down DC-DC buck converter designed for efficient power regulation. It supports a wide input voltage range from 2.5V to 5.5V, making it suitable for various power sources including single Li-polymer cells or multiple alkaline/NiMH cells.
The converter offers an adjustable output voltage, ranging from 0.6V up to the input voltage. It operates at a constant switching frequency of 1.5MHz, ensuring excellent stability and transient response without requiring external compensation components. Key features include internal power switches and synchronous rectification for high efficiency, low quiescent current (40µA typical), and shutdown current less than 1µA.
Integrated protection features such as over-temperature and short-circuit protection, along with under-voltage lockout, help prevent deep battery discharge and ensure reliable operation. The AP3428AKTTR-G1 is available in a compact TSOT-25 package, suitable for surface mount applications.
This device is ideal for post DC-DC voltage regulation in applications like set-top boxes, notebook computers, and PADs. It is designed for high output voltage and high current applications requiring a low dropout threshold, with pulse skip mode for maintaining light-load efficiency.
