MAX6948B: WLED driver with PWM-controllable boost maximizes power efficiency

To save space, the boost converter features a 2MHz switching frequency to minimize the size and cost of external components. It can supply up to 30mA of load current under all conditions. Additionally, the five GPIO ports can function as extra logic ports or as constant-current sink drivers. Capable of accurate current control on parallel LEDs, they feature multiple levels of constant-current drive and are PWM programmable. The ports are ESD protected up to ±8kV HBM to eliminate the need for external ESD-protection circuitry.

The MAX6948B is fully specified over the -40 degrees Celsius to +105 degrees Celsius temperature range. It is available in 25-bump WLP (wafer-level package).
