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 TSSOP-20 packages.
