Introducing the AP3428WT-7 from Diodes Incorporated

The AP3428WT-7 is a cutting-edge, high-efficiency, synchronous rectified step-down converter designed by Diodes Incorporated, a leading global manufacturer and supplier of high-quality semiconductor products. This innovative component is engineered to meet the stringent power requirements of modern portable devices while maintaining a compact form factor, making it an ideal solution for space-constrained applications.

With an input voltage range of 2.7V to 5.5V, the AP3428WT-7 can accommodate a variety of power sources, including single-cell lithium-ion batteries, which are commonly found in portable electronics. Its ability to deliver up to 2A of continuous output current ensures that even demanding devices receive the necessary power for optimal performance.

The device features a high-efficiency synchronous rectification mode of operation, which significantly reduces power loss and improves overall system efficiency. This is particularly beneficial for battery-powered devices, as it extends battery life and reduces the need for frequent charging. The AP3428WT-7 operates at a fixed switching frequency of 1.4MHz, allowing the use of small, low-cost inductors and capacitors, further minimizing the solution size and cost.

Safety is a key consideration in any power management solution, and the AP3428WT-7 incorporates a suite of protective features to ensure reliable operation. These include over-current protection, under-voltage lockout, and thermal shutdown. Additionally, the device supports a Power Good (PG) signal, which provides a real-time indication of the output status, enabling system monitoring and further enhancing the safety and stability of the end application.

The AP3428WT-7 is available in a small, leadless WDFN2020-6 package, which not only saves valuable board space but also enhances thermal performance. Its compact size and high level of integration make it an excellent choice for a wide range of applications, including smartphones, tablets, wireless routers, and other portable and wearable technology.

Diodes Incorporated’s commitment to quality and performance is evident in the AP3428WT-7, making it a top choice for designers looking to optimize their power management solutions with a reliable, efficient, and space-saving converter.
