●● 16-channel LED driver, 60V (max) per channel
●● VIN: 9V to 28V
●● Fully-integrated current-sink FETs with minimum external components
●● Two dynamic external boost or buck controller interfaces to optimize system power efficiency
●● Patented BroadLED™ digital adaptive switch mode technology for high current matching at maximum efficiency xx Channel-to-channel matching accuracy ±2% xx Enables use of cheaper, loosely binned LED arrays for lower BOM cost
●● High-speed PWM dimming via SPI interface xx High-bandwidth PWM-based dynamic local dimming xx PLL-locked VSYNC synchronized PWM xx Dimming range: 1% to 99.
9%, 12-bit resolution xx Dimming frequency support for NTSC, PAL and 3D game modes with 5-bit programmability in normal mode (controlled by SPI dimming interface)
●● Direct and unsynchronized dimming via external PWM
●● Per-channel current xx Up to 150mA aver...
