MAX845ESA-T Description

Short technical summary and product information.

The MAX845ESA-T is an integrated circuit designed to provide an isolated power supply, suitable for thin PCMCIA cards and other space-constrained applications. It drives a center-tapped transformer primary from a 5V or 3.3V DC power supply, allowing the secondary to be wound for various isolated positive or negative voltages up to 750mW.

 

Key features include a minimum switching frequency of 450kHz, ultra-low input supply current ripple, and a low-power shutdown mode consuming only 5µW. The device operates from a single +5V or +3.3V supply and is available in an 8-pin SOIC package.

 

This transformer driver is ideal for applications requiring isolated power, such as isolated data acquisition, interface power supplies, noise-immunity communications, and bridging ground differences. Its compact size and efficient operation make it a versatile component for portable and embedded systems.

 

The MAX845ESA-T is surface-mountable in an 8-SOIC package, facilitating integration into compact PCB designs.
