Note: Maximum non-continuous currents rates as short pulses (t < 1s). Exposure to maximum rating conditions for extended periods may affect device reliability.
BOOST STANDBY MODE
User can set the Boost Converter to STANDBY mode by
writing the register bit EN_BOOST low. When EN_BOOST is
written high, the converter starts for 20ms in low current
PWM mode and then goes to normal PWM mode. All LED
outputs are off during the 20ms delay to ensure smooth
startup.
BOOST OUTPUT VOLTAGE CONTROL
User can control the boost output voltage by Boost Output
8-bit register.
