Recommended Layout
When the driver is in the 1.5x charge pump mode, the
1 MHz switching frequency operation requires to minimize
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 Cin and Cout require short connection to ground
which can be done with multiple vias as shown on Figure 24.
A square copper area matches the QFN16 exposed pad
(GND) and must be connected to the ground plane
underneath. The use of multiple via will improve the heat
dissipation.
