Power Supply Recommendations

A low-ESR/ESL ceramic capacitor must be connected close to the IC, between VDD and GND pins to support the high peak current being drawn from VDD during turnon of the FETs. It is most desirable to place the VDD decoupling capacitor on the same side of the PC board as the driver. The inductance of via holes can impose excessive ringing on the IC pins.

TI recommends the use of a three-terminal capacitor connecting in shunt-through manner to achieve the lowest ESL and best transient performance. This capacitor can be placed as close as possible to the IC, while another capacitor in larger capacitance can be placed closely to the three-terminal cap to supply enough charge but with slightly lower bandwidth. As a general practice, the combination of a 0.1 µF of 0402 or feed-through capacitor (closest to LMG1025-Q1) and a 1 µF 0603 capacitor is recommended.
