16-Channel 50mA Buck LED Driver with Dot Correction & Gray Scale Dimming
16-Channel 50mA Buck LED Driver with Dot Correction & Gray Scale Dimming Linear Technology announces the LT3745, a 16-channel LED driver integrated with a 55V step-down controller. The LED driver powers up to 75mA of LED current for each channel, which can drive up to 36V of LEDs in series, making it ideal for applications such as large LED billboards. Each channel has individual 6-bit dot correction current adjustment and 12-bit gray scale PWM dimming. Combined with a 0.5μs minimum LED on-time, the LT3745 offers very wide dynamic contrast ratios. Both dot correction and gray scale dimming are accessible via a serial interface in TTL/CMOS logic. The LT3745’s 6V to 55V input voltage range is well suited for a wide range of input sources found in commercial and industrial designs, typically between 12V and 48V. The combination of minimal externals and a 6mm x 6mm QFN package provide a highly compact solution footprint for multichannel LED applications. Read more »
