MAX845EUA+ Description

Short technical summary and product information.

The MAX845EUA+ is an isolated transformer driver IC from Maxim Integrated, suitable for creating isolated power supplies in compact applications such as PCMCIA modem cards. It drives a center-tapped transformer primary from a 5V or 3.3V DC input, allowing for various isolated secondary voltages up to 750mW.

 

Key features include a minimum switching frequency of 450kHz, which enables the use of miniature output capacitors, and an ultra-low input supply current ripple. The device also incorporates a low-power shutdown mode, consuming only 5µW, which is beneficial for battery-powered devices. It is available in an 8-pin SO and µMAX package, designed for surface mounting.

 

This component is ideal for applications requiring isolated interfaces, noise-immunity, or bridging ground differences. Its design facilitates the creation of compact, isolated DC-to-DC power supplies for portable and space-constrained electronic systems.
