VS compensation (duty cycle adjustment) module
All stand-alone HS outputs can be programmed to calculate some internal duty cycle
adjustment to adapt the duty cycle to a changing supply voltage at VS. This feature is aimed
to avoid LED brightness flickering in case of alternating supply voltage. The correction of the
duty cycle is based on the following formula:
Equation 1: Duty cycle correction
Vth = Duty cycle reference voltage: defined as 10 V
VBat = Reference voltage: defined as voltage at pin VS
VLED = Voltage drop on the external LED
DCnom = Nominal Duty Cycle programmed by SPI< PWMx DCx>
To be compatible to different LED load characteristics the value for VLED can be
programmed for each output by a dedicated control register OUT7_VLED …
OUT_HS_VLED (CR 18 to CR 22). Auto compensation features can be activated for all HS
outputs each by setting OUTx_AUTOCOMP_EN (CR 18 to CR 22).
The programmed LED voltage (OUTx_V_LED (CR18 to CR22)) must be lower than Vth
(10 V).
