PF7804 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.
