1A High-Brightness LED Driver with Integrated NMOS Switch
REV：00
General Description
The LD7860 is a controller for step-down converters,
operating in continuous conduction mode and ideally for
driving high brightness of power LEDs. The device
operates with inputs from 6V to 30V and utilizes an
external high-side current sense resistor to set the normal
average output current of up to 1A. Depending on the
selection of input voltage and external components, it can
drive up to 7pcs of WLEDs (VF=3.5V). Output current can
be adjusted below the set value, by applying an external
analog or PWM control signal to DIM pin. The device can
operate with the switching frequency of up to 1MHz,
making it ideal for the applications requiring small footprint
and low value external inductors. Some additional
features include under-voltage lockout, over current
protection and thermal shutdown.
