PAM2842
High Power LED Driver
Description
The PAM2842 is a high power LED driver,
capable of driving up to 10 high power LEDs in
series. The PAM2842 supports buck, boost and
sepic topology.
The PAM2842 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 using a PWM signal
to the COMP pin.
The PAM2842 is available in 40-Pin QFN6x6 and
TSSOP-20 packages.
