VDRM - Variable Step Down Regulator Module
J CIRCUIT DESCRIPTION
This reduces any voltage drops on the input or output of the converter and maximizes efficiency. To optimize voltage
accuracy at the load, ensure that a separate feedback voltage sense trace is made to the load. Doing so will correct
for voltage drops and provide optimum output accuracy.
5: Provide adequate device heat-sinking.
Use an array of heat-sinking vias to connect the exposed pad to the ground plane on the bottom PCB layer. If the
PCB has a plurality of copper layers, these thermal vias can also be employed to make connection to inner layer
heat-spreading ground planes. For best results use a 6 x 6 via array with minimum via diameter of 254μm thermal
vias spaced 1.5mm. Ensure enough copper area is used for heat-sinking to keep the junction temperature below
125°C.
