The AP3429AKTTR-G1 from Diodes Incorporated is a 2A step-down DC-DC buck converter designed for efficient power conversion. It supports an input voltage range of 2.7V to 5.5V, making it suitable for various power sources including single Li+/Li- polymer cells or multiple Alkaline/NiMH cells.
The output voltage is adjustable from 0.6V up to the input voltage, providing flexibility for different application requirements. This converter operates at a 1MHz switching frequency and features internal power switches and synchronous rectifiers to minimize external component count and maximize efficiency. It consumes only 90μA of no-load quiescent current and has a shutdown current of less than 1μA.
Key features include over-temperature protection, short circuit protection, and under-voltage lockout to prevent deep battery discharge. The AP3429AKTTR-G1 is available in a compact TSOT25 package, suitable for surface mount applications. Its design requires no external compensation components, simplifying circuit design.
Applications include point-of-load conversion for 5V or 3.3V systems, telecom and networking equipment, set-top boxes, storage equipment, video cards, and DDR power supplies.
