Overview

19-4935; Rev 0; 9/09 TION KIT EVALUA BLE A IL A V A High-Efficiency PWM LED Driver with Boost Converter and Five Constant-Current GPIO Ports General Description The MAX6948B general-purpose input/output (GPIO) peripheral drives a series string of white LEDs (WLEDs), and contains up to five general-purpose input/output (GPIO) ports to drive additional LEDs.
The integrated 2MHz boost converter minimizes the size and cost of external components and supplies 30mA of load current at up to 28V.
The converter is stable under all load conditions from 5V up to 28V and includes open-circuit detection to prevent damage to the IC.
An I2C-programmable 10-bit pulse-width modulation (PWM) signal enables ...
