The MAX1554ETA+T is a high-efficiency, 40V step-up converter from Analog Devices / Maxim Integrated, specifically designed for driving 2 to 10 white LEDs in series for display backlighting. 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 offers a current limit of 970mA for driving up to 10 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 MAX1554ETA+T is available in a space-saving 8-pin TDFN 3mm x 3mm package, suitable for compact designs. Its small, low-profile external components contribute to a flexible and integrated solution for a wide range of backlighting applications in cellular phones, PDAs, and other handheld devices.
