The MAX1553ETA+T is a high-efficiency, 40V step-up converter designed for backlighting applications in portable devices such as cellular phones and PDAs. It integrates a 40V N-channel MOSFET switch for high efficiency and extended battery life.
This converter offers constant-current regulation for even LED illumination. The MAX1553 variant has a current limit of 480mA for driving two to six white LEDs, while the MAX1554 variant supports up to 10 white LEDs with a 970mA current limit. Brightness can be adjusted using a single analog or 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 TDFN 3mm x 3mm package, suitable for compact designs. It operates within a 2.7V to 5.5V input voltage range and achieves high efficiency, up to 88% when driving 6 LEDs.
Key features include analog or PWM control of LED intensity, optimized low input ripple, and small, low-profile external components. The device is suitable for color display backlighting in a wide range of handheld devices.
The input voltage range is 2.7V to 5.5V.
The device is a 40V step-up converter.
The current limit for the MAX1554 is 970mA.
The current limit for the MAX1553 is 480mA.
The operating temperature range is -40°C to +85°C.
The MAX1553ETA+T is supplied in an 8-pin TDFN 3mm x 3mm package.
