The TPS61196 provides a highly integrated solution for LCD TV backlight with an independent PWM dimming
function for each string. This device is a current mode boost controller driving up to six WLED strings with
multiple LEDs in series. Each string has an independent current regulator providing a LED current adjustable
from 50 mA to 400 mA within ±1.5% matching accuracy. The minimal voltage at the current sink is
programmable in the range of 0.3 V to 1 V to fit with different LED current settings. The input voltage range for
the device is from 8 V to 30 V.
数据表上有这么一段,TPS61196最小只能50mA吗?还是通过ISET设置最低只能50mA?如果采用PWM控制能不能做到更低?
