13 / 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 13 / 69 Figure 6. Multiple strings with segment driving configuration application diagram Polarity must be respected in the internal MOSFET. 8.2 LED current capability and power dissipation The LED string current is provided by a separate buck or boost converter. The specifications of the matrix controller are matched to the multichannel buck converter ASLx41xSHN. The MLC can also be driven by other buck driver or constant current suppliers. One buck converter output supplies the current for one LED string. For the MLC, the maximum LED string voltage is 57 V, maximum LED string current is 1.5 A in serial configuration, and up to 6 A in parallel configuration for ASL5x15yHzpart numbers. For part numbers ASL5x08yHz, the maximum LED string current is 0.8 A, in serial configuration, and up to 3.2 A when paralleling all switches' blocks. The internal power dissipation depends on the number of LEDs that are bypassed. The maximum dissipation in the Matrix LED Controller occurs when all switches are closed with 1.5 A LED current through them, the dissipation is estimated to be 5 W at 120 °C junction temperature. 8.3 Internal PWM dimming generator and phase shifting The ASL5015yHz and ASL5008yHz part numbers have an internal PWM generator module for each channel. The PWM has 12-bit resolution, which means a time accuracy |
