The MAX749CSA-T is a specialized power management integrated circuit designed for generating negative LCD-bias contrast voltages. It accepts input voltages ranging from 2V to 6V and offers digital adjustability of the output voltage in 64 steps via an internal DAC. The device requires minimal external components, making it suitable for space-constrained applications.
Key electrical characteristics include a low quiescent current of 60µA maximum, which reduces to under 15µA in shutdown mode. The switching frequency can reach up to 500kHz, enabling the use of small external components. The MAX749CSA-T is available in an 8-SOIC package and operates within a temperature range of 0°C to 70°C.
This IC is well-suited for portable electronic devices such as notebook computers, palmtop computers, and personal digital assistants where efficient and flexible LCD bias voltage generation is required. Its flexible control options, including digital, potentiometer, and PWM adjustment, allow for easy integration into various designs.
