LAYOUT CONSIDERATIONS

GROUNDING AND CIRCUIT LAYOUT CONSIDERATIONS

The TPS4005x provides separate signal ground (SGND) and power ground (PGND) pins. It is important that

circuit grounds are properly separated. Each ground should consist of a plane to minimize its impedance if

possible. The high power

noisy

circuits such as the output, synchronous rectifier, MOSFET driver decoupling

capacitor (BP10), and the input capacitor should be connected to PGND plane at the input capacitor.

Sensitive nodes such as the FB resistor divider, R

T

, and ILIM should be connected to the SGND plane. The

SGND plane should only make a single point connection to the PGND plane.

Component placement should ensure that bypass capacitors (BP10 and BP5) are located as close as possible

to their respective power and ground pins. Also, sensitive circuits such as FB, RT and ILIM should not be located

near high dv/dt nodes such as HDRV, LDRV, BOOST, and the switch node (SW).
