MAX1553, MAX1554 High-Efficiency, 40V Step-Up Converters For 2 To 10 White LEDs

The MAX1553 MAX1554 drive white LEDs in series with a constant current to provide efficient Display backlighting in cellular phones, PDAs, and other hand-held devices. The Step-up converter includes an internal 40V, low RDSON, N-Channel MOSFET Switch for high efficiency and maximum battery life. The MAX1553 has a current limit of 480mA for driving two to six white LEDs while the MAX1554 has a current limit of 970mA for driving up to 10 white LEDs
A single Analog PWM Dual Mode" input provides two simple means of brightness adjustment. A separate enable input provides on/off control. Soft-start minimizes inrush current during startup.
The MAX1553 MAX1554 are available in space-saving 8-pin TDFN 3mm x 3mm packages.
