The MAX845EUA+ is an integrated circuit designed by Analog Devices to provide an isolated power supply suitable for thin PCMCIA cards and other space-constrained applications. It functions as a transformer driver, utilizing a 5V or 3.3V DC power supply to drive a low-profile center-tapped transformer primary. The secondary winding can be configured to deliver various isolated positive or negative voltages with power up to 750mW.
Key features include a minimum switching frequency of 450kHz, ultra-low input supply current ripple, and a single +5V or +3.3V supply capability. It also offers a low-power shutdown mode, consuming only 5µW, which disables the switches and oscillator to reduce power consumption. The device is available in an 8-pin SO and µMAX package, with a surface mount type.
Applications for the MAX845EUA+ include isolated data acquisition, isolated interface power supplies, noise-immunity communications interfaces, bridging ground differences, medical equipment, process control, and low-power LAN networks. Its design is optimized for driving ultra-thin 5V-µs transformers, making it ideal for isolated DC-to-DC power supplies in PCMCIA applications.
