EUP3409JIR1 Description

Short technical summary and product information.

The EUTECH EUP3409JIR1 is a highly efficient dual synchronous step-down converter designed for portable applications. Each of its two independent converters operates at a constant 1.5MHz frequency, capable of delivering up to 800mA of load current. The input voltage range is from 2.5V to 5.5V, with an output voltage adjustable as low as 0.6V.

 

This converter integrates main switches and synchronous rectifiers, eliminating the need for external Schottky diodes and contributing to up to 96% efficiency. It supports 100% duty cycle operation for low dropout conditions and includes features like short circuit protection and thermal fault protection. The device comes in a space-saving 10-pin TDFN package, suitable for surface mounting.

 

Applications for the EUP3409JIR1 include power supplies for cellular phones, microprocessors, PDAs, portable media players, wireless modems, and digital cameras. Its compact size and high efficiency make it ideal for battery-powered devices where space and power consumption are critical.
