AP3428DNTR-G1 Description

Short technical summary and product information.

The AP3428DNTR-G1 from Diodes Incorporated is a 1A step-down DC-DC converter designed for efficient power regulation. It supports an input voltage range of 2.5V to 5.5V, making it suitable for various power sources including single Li-polymer cells or multiple alkaline/NiMH cells.

 

This buck converter features an adjustable output voltage from 0.6V up to the input voltage. With a constant switching frequency of 1.5MHz, it offers excellent stability and transient response without requiring external compensation components. Key electrical characteristics include a low quiescent current of 40µA (typical) at no load and a shutdown current of less than 1µA.

 

Integrated power switches and synchronous rectifiers minimize external component count and enhance efficiency. The device includes over-temperature and short-circuit protection, along with under-voltage lockout to protect batteries. It is available in a compact U-DFN2020-6 package, suitable for surface mount applications.

 

The AP3428DNTR-G1 is RoHS3 compliant, lead-free, and halogen-free, aligning with environmental standards.
