Decoupling capacitor - logic supply. Decoupling capacitor - load supply. Power ground for the sense resistor, R S , should be connected as close to the device as possible. Also, R S should be non-inductive, and the circuit board ground run should be as large as physically possible. Use external Schottky diodes in parallel with the internal diodes.
Heat sinks are also a possibility.
However, Schottky diodes are typically the preferred solution. One divider can be used to generate the V REF signal. These pins can be tied together since the internal DAC takes the external signal and processes it. One divider can also be used to provide both PFD inputs, provided that the user does not change modes, i.e. fast, slow, or mixed. To dynamically change the PFD input, the user will have to provide external signals.
