MAX1945REUI+T Description

Short technical summary and product information.

The MAX1945REUI+T is a step-down switching regulator designed for high-density distributed power supplies. It operates from an input voltage range of 2.6V to 5.5V and can deliver up to 6A of output current.

 

Key electrical specifications include a selectable switching frequency of 400kHz to 1.2MHz, allowing for small external components. The output voltage is adjustable from 0.8V to 85% of the input voltage, with preset options of 1.8V or 2.5V. It boasts ±1% output accuracy over load, line, and temperature variations. The device also offers voltage margining capabilities: ±4% for the MAX1945R variant.

 

This regulator is housed in a 28-pin TSSOP-EP package, suitable for surface mounting. It is specified for operation over an industrial temperature range of -40°C to +85°C. The internal dual N-channel MOSFETs help lower heat dissipation at heavy loads, and two devices can operate 180 degrees out-of-phase to minimize input capacitance.
