MAX845ESA Description

Short technical summary and product information.

The MAX845ESA 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 input, allowing the secondary to be wound for any isolated positive or negative voltage 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 is housed in an 8-pin SOIC package, making it ideal for compact designs. Its output ripple is low enough to permit the use of miniature output capacitors.

 

Applications for the MAX845ESA include PCMCIA modem cards, isolated data acquisition, isolated interface power supplies, noise-immunity communications interfaces, bridging ground differences, medical equipment, process control, and low-power LAN networks.
