PWM LED driver circuit MAX6948B

This PWM LED driver circuit is designed using the MAX6948B PWM LED driver which has an integrated 2MHz boost converter that minimizes the size and cost of external components and supplies 30mA of load current at up to 28V.
The PWM LED driver circuit 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.

Two of the ports drive addi­tional LEDs up to 30mA/port, while the other three ports drive LEDs at up to 10mA/port.
