GENERAL DESCRIPTION
The PF7804 is a 70V, 4-channel LED driver which
integrates current-programmable power MOSFETs
and a boost controller. The adjustable switching
frequency of the boost controller offers the flexibility
for the design trade-off between EMI performance and
efficiency. The LED is adjustable from 20mA to
160mA by ISET resistor.
Furthermore, the embedded boost over current
protection, open LED lamp protection, short LED lamp
protection, and over temperature protection provide
the users a highly integration solution as well as to
reduce the part counts and required PCB space.
SOP-16 and DIP-16 are offered for the PF7804.
