10 Layout
10.1 Layout Guidelines
- Place a low ESR and ESL decoupling capacitor CREF in the 1-µF to 2.2-µF range, preferably ceramic, from VREF pin to GND.
- The EA+ is a non-inverting input, the EA– is an inverting input and the COMP is the output of the error amplifier. Place resistor and capacitor series network between EA+ pin and COMP pin, and reduce the trace of resistor and capacitor series network as much as possible.
- Place a low ESR and ESL capacitor CT, preferably ceramic, from CT pin to GND, and place CT close to UCx846/7 as much as possible.
- Place a resistor RT from RT pin to GND, and place RT close to UCx846/7 as much as possible.
