Additional preview pages of the PAM2845 datasheet.

The PAM2845 is a high-efficiency boost type LED driver.

It is designed for large LCD panel that employs an array of LEDs as back light source.

The PAM2845 employs a current-mode step-up converter that drives six parallel strings of LEDs connected in multiple series.

n Six Constant-Current Output Channels n Parallel Channels Allow Higher Current per LED String n Maximum 40V Continuous Voltage Output Limit for Each Channel n Adjustable Constant Output Voltage n Adjustable Constant LED Current n Drives 10 or more LEDs Each String as Long as the String Voltage Less Than 40V n Internal 2.5A Power MOSFET n Allows Digital PWM and Analog Dimming n Wide (100:1) PWM Dimming Range without Color Shift n Independent Dimming and Shutdown Control of the LED Driver n ±1% T.
