Описание
Digitally controlled LED driver board for automotive lighting applications. LED driver board is designed for high brightness automotive LED front lighting applications according to the AutoDevKit initiative. It can control four LED strings through two embedded L99LD21 flexible LED drivers with high efficiency boost controller and two embedded buck converters. The boost controller section in each L99LD21 LED driver integrates a high current gate driver for an external N-channel MOSFET and delivers a constant output voltage to two integrated buck converters. The boost controller of two devices can be stacked to allow dual phase operation for high power applications, with an interleaving pattern for improved input current ripple and current load sharing. The buck converter integrates an N-channel MOSFET driven by a bootstrap circuit.
• Two embedded L99LD21 high power LED drivers able to supply four independent channels
• Output current up to 1.69A each channel
• Input operating voltage range from 5.5V to 24V
• Programmable via SPI allowing accurate LED current setting
• Protections and diagnostics for output short-circuit/open-load/overtemperature/battery undervoltage
• Automotive limp-home mode support
• Board size is 81 x 100mm, maximum components height of 11mm
• All ST components are qualified Automotive grade
• Board designed according to the AutoDevKit initiative
