The AP3429/A is a 2A step-down DC-DC buck converter from Diodes Incorporated. It supports an input voltage range of 2.7V to 5.5V, making it suitable for single Li+/Li-polymer cells or multiple Alkaline/NiMH cells. The output voltage is adjustable from 0.6V up to the input voltage.
This converter utilizes internal power switches and a synchronous rectifier to achieve high efficiency and minimize external component count. It operates at a constant frequency of 1MHz, providing excellent stability and transient response without requiring external compensation components. Key features include over-temperature protection, short circuit protection (Latch Off or Hiccup Mode depending on variant), and under-voltage lockout.
The AP3429/A is available in a compact TSOT25 package, ideal for space-constrained applications. Its low quiescent current of 90μA and shutdown current of less than 1μA contribute to power efficiency. Applications include point-of-load conversion for 5V or 3.3V systems, telecom/networking equipment, set-top boxes, storage equipment, video cards, and DDR power supplies.
