14 / 69 page  NXP Semiconductors ASL5xxxyHz Matrix LED Controller (MLC) ASL5xxxyHz All information provided in this document is subject to legal disclaimers. © NXP B.V. 2019. All rights reserved. Product data sheet Rev. 2.1 — 5 February 2019 14 / 69 of 4.1 ms/4096 = 1 µs , at 244 Hz or 0.5 µs, at 488 Hz. The resolution in terms of PWM percentage is 0.024 %. This resolution ensures very smooth LED dimming to very low light levels. When a PWM switch turns on, the forward voltage of the whole string decreases with the Vf of one LED. During the negative slope, there could be a high discharge current from the string capacitor that also flows through the entire LED string. If more than one LED is bypassed at the same time, then this injected current is higher when additional LEDs are bypassed. Therefore, it is desired to close only one switch at a time. For that reason, the MLC incorporates an internal phase-shifting module that ensures closing switches one at a time. Note: Automated phase shifting feature is applicable to all Matrix LED controllers part numbers. Figure 7 shows a phase-shifting example in an MLC IC, during just one PWM cycle. Figure 7.
