MAX1831EEE Description

Short technical summary and product information.

The MAX1831EEE from Analog Devices is a constant-off-time, pulse-width-modulated (PWM) step-down DC-DC converter designed for low-voltage conversion in applications like notebook computers. It features internal synchronous rectification for high efficiency, eliminating the need for an external Schottky diode.

 

This device can deliver continuous load currents up to 3A. It offers an adjustable output voltage from +1.1V to VIN and also supports pin-selectable outputs of +3.3V, +2.5V, and +1.5V. The switching frequency can be programmed up to 1MHz, allowing for optimization of performance trade-offs between efficiency, noise, component size, and cost. The MAX1831EEE achieves efficiencies as high as 94% and includes features like Idle Mode™ for light-load efficiency, internal digital soft-start, and a low-power shutdown mode.

 

The MAX1831EEE is available in a 16-pin QSOP package and is designed for surface mount applications. Its operating temperature range is -40°C to +85°C.
