10.1 Layout Guidelines

Four-layer layout is recommended

A 1-µF ceramic decoupling capacitor is recommended, to be placed as close as possible between the VCC terminal and GND, and tracked directly to both terminals.

Place CSS, RDT, Rp, Cp, RT1, and RT2 as close as possible to the UCC25600.

Connect a regulated bias supply to the VCC pin.
