Title: Printed circuit board for integrated LED driver

Abstract

A light emitting diode (LED) module may include a direct current (DC) voltage node formed on a first layer. The DC voltage node may be configured to sink a first current. One or more devices may be formed on the first layer configured to provide a second current to one or more LEDs. A device of the one or more devices may carry a steep slope voltage waveform. A local shielding area may be formed in a second layer directly below the DC voltage node and the one or more devices. The local shielding area may include a substantially continuous area of conductive material. A conductive via may extend through one or more layers. The conductive via may electrically connect the DC voltage node and the local shielding area.
