MAX1771ESA Description

Short technical summary and product information.

The MAX1771ESA is a versatile DC DC switching controller from Analog Devices, capable of performing both step-up and step-up/step-down voltage conversion. It is designed for applications requiring high efficiency, achieving up to 90% over a load range of 30mA to 2A. The device operates with an input voltage range from 3V to 16.5V and features a high switching frequency of up to 300kHz, allowing for the use of miniature surface-mount magnetics.

 

This controller utilizes a unique current-limited pulse-frequency-modulation (PFM) control scheme, offering the benefits of PWM converters with significantly lower supply current, typically under 110µA. It drives an external N-channel MOSFET switch, enabling output power up to 24W. The MAX1771ESA is suitable for battery-powered applications and portable devices, including positive LCD-bias generators, flash memory programmers, and high-power RF power-amplifier supplies.

 

The MAX1771ESA is supplied in an 8-SOIC package and is designed for surface-mount applications. It operates within a temperature range of -40°C to 85°C. The device offers an enable control feature and a preset or adjustable output voltage capability.
