PAM2841
1.5A SW CURRENT, 40V PRECISION WLED DRIVER
Description
The PAM2841 is a white LED driver, capable of driving 10 or more
WLEDs in series (depending on forward voltage of the LEDs) with a
range of input voltages from 2.7V to 5.5V.
The PAM2841 features over current protection, over voltage
protection, under voltage lockout and over temperature protection,
which prevent the device from damage.
LED dimming can be done by four methods as described in the
Application Information hereinafter.
