LMR64010: adding a zero to the loop response

Part Number: LMR64010


Team,

Please help answer my customer's question:

I was looking at a design using the LMR64010 for a simple boost circuit and was noticing the section regarding adding a zero to the loop response with a feed forward capacitor. The target for the zero is 8KHz and my R1 value is 332K, which calculates out to 60pF, which, of course, is not a standard value. So if I move to a standard value (56pF or 68pF) I can move the zero to either approximately 7KHz or 8.5KHz. Is it preferential to move the zero up? Or down?

Thanks

Viktorija
