High-Efficiency PWM LED Driver With Boost Converter And Five Constant-Current GPIO PortsThe 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 1024 levels of WLED intensity. By Maxim Integrated Products
