DLPS039G December 2015 – July 2024 TPS99000-Q1
PRODUCTION DATA
Although the blanking current control makes the TPS99000-Q1-based systems less susceptible to ill effects from input voltage variations, it is still recommended that a stable, preregulation voltage source be used to supply the VLED power rail (as shown in the functional block diagram). Changes in input voltage to the driver will have impact on slew rates or rising edges of ripple waveforms in continuous operation mode. These variations will slightly alter the total integrated light output per pulse, which can cause noticeable variations in color balance and brightness as input voltage changes.
