Master Switch for both RGB Drivers:
RGB_START = 0
→
RGB OFF
RGB_START = 1
→
RGB ON, starts the new cycle from t = 0
RGB_PWM = 0
→
RSW, GWS and BSW control directly the RGB outputs (on/off control only)
RGB_PWM = 1
→
Normal PWM RGB functionality (duty, slope, on/off times, cycle)
Flash Mode enable controls for RGB1 and RGB2. In Flash mode (EN_FLASH = 1) RGB outputs are
PWM controlled simultaneously, not in 3-phase system as in the Normal Mode.
XX_PWM = 0
→
External PWM control from PWM_LED pin is disabled
XX_PWM = 1
→
External PWM control from PWM_LED pin is enabled
Internal PWM control (DUTY) can be used independently of external PWM control. External PWM has
the same effect on all enabled outputs.

PWM_LED input can be used as direct on/off or brightness (PWM) control. If PWM_LED input is not used, it must be tied to V
DD_IO

Note 15:
Application Note 1291, “Driving RGB LEDs Using LP3933 Lighting Management System” contains a thorough description of the RGB driver functionality
including programming examples.
WLED Driver (WLED1...4)
White LED (WLED) driver drives each white LED with a
regulated constant current. The amount of the current is
controlled by the 8-bit current mode DAC from 0 to 25.5mA
in 0.1mA steps.
20080527
CLED Driver (CLED1…2)
The current of CLEDs (Caller ID display backlight LEDs) can
be adjusted by 8-bit current mode DAC. WLED and CLED
can be used to drive any kind of LED.
20080504
Enables
WLED and CLED enable is controlled from user register.
PWM control of WLED and CLED (for dimming etc.) is
possible using PWM_LED pin together with WLED_PWM
and CLED_PWM enable control from user register.
