PCB Layout
When the driver is in the 1.5X charge pump
mode, the 1MHz switching frequency operation
requires to minimize the trace length and
impedance to ground on all 4 capacitors. A
ground plane should cover the area on the
bottom side of the PCB opposite to the IC and the
bypass capacitors. Capacitors C and Co should
be short connected to ground with multiple vias
as shown on Figure4.
Square copper area matches the QFN 16
exposed pad (GND) which is connected by a
trace to the pin 12 pad (GND). A large via
(metalized hole) centered in the square pad
provides a low impedance connection to the
ground plane on the opposite side of the PCB and
allows the heat dissipation of the LED driver to
achieve excellent thermal performance.
