MAX1553ETA+T Description

Short technical summary and product information.

The MAX1553ETA+T is a high-efficiency, 40V step-up converter designed for driving white LEDs in series for display backlighting in portable devices. It provides constant-current regulation for uniform LED illumination and features an internal 40V N-channel MOSFET switch for high efficiency and extended battery life.

 

This device operates with an input voltage range of 2.7V to 5.5V and has a current limit of 480mA, suitable for driving two to six white LEDs. Brightness adjustment is managed through a single analog/PWM Dual Mode input, with a separate enable input for on/off control. Soft-start functionality minimizes inrush current during startup.

 

The MAX1553ETA+T is available in a space-saving 8-pin WDFN exposed pad package, designed for surface mounting. Its compact size and low-profile external components make it ideal for applications where space is limited, such as cellular phones and PDAs.

 

Key features include high efficiency, optimized low input ripple, and flexible brightness control, making it a versatile solution for various backlighting applications.
