MAX686EEE+T Description

Short technical summary and product information.

The MAX686EEE+T is a versatile DAC-controlled boost/inverter integrated circuit from Analog Devices, specifically designed to provide positive or negative LCD bias voltages. It can generate output voltages up to +27.5V or -27.5V, making it suitable for a wide range of display requirements.

 

Key features include an internal 6-bit digital-to-analog converter (DAC) for precise digital adjustment of the output voltage, an internal N-channel MOSFET switch rated for 500mA and 28V, and a high switching frequency of up to 300kHz. This high frequency allows for the use of small external components, contributing to a compact design. The device operates with an input voltage range of +2.7V to +5.5V for the IC and +0.8V to +27.5V for the inductor.

 

With a typical quiescent supply current of 65µA and a shutdown current of 1.5µA, the MAX686EEE+T is an excellent choice for battery-powered portable equipment, helping to extend battery life. It also includes an LCDON output for automatic disabling of the LCD bias voltage when the display logic voltage is removed, protecting the display. The IC is housed in a small 16-pin QSOP package, offering space savings.

 

Applications for the MAX686EEE+T include positive or negative LCD bias in personal digital assistants, notebook computers, portable data-collection terminals, palmtop computers, and for varactor tuning diode bias.
