使用内置用于白光 LED 的 6 通道
灌电流驱动器的 TB62754AFNG 升压 DC-DC
控制器（6 通道输出的情况）的典型应用。 TB62754AFNG是一款专为白光LED恒流驱动而设计的高效升压型
DC/DC控制器。该IC通过将多个LED串联而成的白光LED分成6条线，以
恒定电流驱动白光LED。 LED 电流 (IF) 通过外部电阻设置，并且可通过 PWM 信号进行调光控制。该IC专门用于驱动大型LCD中的背光白光LED
说明
-
Typical Application for (Case of 6Ch Outputs) Using TB62754AFNG Step-Up DC-DC Controller built in 6Ch sink driver for White LED. The TB62754AFNG is a high efficient step-up type DC/DC controller specially designed for constant current drive of white LED. This IC can drive white LEDs with constant current by dividing white LEDs, which are serial connected with lots of LEDs, into 6 lines. LED current (IF) is set with an external resistor and dimming control is available by PWM signal. This IC is especially for driving back light white LEDs in large LCD
