4 Board Layout
through
show the board layout for the LM76005QEVM. The EVM offers resistors,
capacitors, and test points to configure the output voltage and precision enable pin, and set frequency and
external clock synchronization.
The RNP WQFN-30 package offers an exposed thermal pad which must be soldered to the copper landing on
the PCB for optimal thermal performance. The PCB consists of a 4-layer design. There are 2-oz copper planes
on the top and bottom and 1-oz copper mid-layer planes to dissipate heat with an array of thermal vias under the
thermal pad to connect to all four layers.
Test points have been provided for ease of use to connect the power supply and required load, and monitor
critical signals.
