Grounding is an important part of the layout. The device has a PGND and a GND pin. The GND pin is the quiet
analog ground of the device and should have its own separate ground pour; connect the quiet signals to GND
including the RILIM resistor and any input decoupling capacitors to the GND pour. It is important that the RILIM
resistor be tied to a quiet ground to avoid unwanted shifts in the current-limit threshold. The PGND pin is the
high-current power-stage ground; the ground pours of the output (AUX) and bulk input capacitors should be tied
to PGND. PGND and GND should to be tied together in one location at the IC thermal pad, creating a star-point
ground.
The output filter of the boost converter is also critical for layout. The inductor and AUX capacitors should be
placed to minimize the area of current loop through AUX–PGND–SW.
The layout for the TPS2500EVM evaluation board (HPA337) is shown in Figure 21 and should be followed as
closely as possible for best performance. The key components are inside the white silkscreen box.
