使用內置用于白光 LED 的 6 通道
灌電流驅動器的 TB62754AFNG 升壓 DC-DC
控制器（6 通道輸出的情況）的典型應用。 TB62754AFNG是一款專為白光LED恒流驅動而設計的高效升壓型DC/DC控制器。該IC通過將多個LED串聯而成的白光LED分成6條線，以
恒定電流驅動白光LED。 LED
電流 (IF) 通過外部電阻設置，并且可通過 PWM 信號進行調光控制。該IC專門用于驅動大型LCD中的背光白光LED

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
