LD7890 11/5/2013 High Voltage 4-Channel LED Controller Driver REV: 01 General Description The LD7890 is a 4-channel LED controller with a boost switching controller. It’s an ideal solution for driving high power LED backlights. The LD7890 can deliver high accuracy of constant current to 4 individual LED strings with 4 External MOSFET without cross-reference. The LD7890 is designed for Current-Mode Boost Controller, capable to operate over a wide range VIN from 9V to 28V and build in the High voltage MOSFET gate to reduce external Power MOSFET thermal issue. The other features include LED short and open protection, cycle by cycle current limit, and thermal shutdown.
