The MAX845ESA+T is an integrated circuit designed by Analog Devices / Maxim Integrated to provide an isolated power supply. It is small enough to fit in thin PCMCIA cards and other space-sensitive applications. The device drives a low-profile center-tapped transformer primary from a 5V or 3.3V DC power supply, with the secondary capable of providing 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 single +5V or +3.3V supply operation. It also offers a low-power shutdown mode consuming only 5µW. The MAX845ESA+T is available in an 8-pin SOIC package and operates over a temperature range of -40°C to +85°C.
Applications for this transformer driver 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. Its design allows for low output ripple, permitting the use of miniature output capacitors.
