About fsw selection of TPS53219A, please let me check two points below.
①Is relation of fsw and RRF value, linear or 8-steps?
(For example, RRF：200kΩ to VREG ⇒about 800kHz, it is relation of linear)
②If ① is 8-steps, please let me know about RRF required accuracy.
【Background】
Customer want to use 820kΩ ±5% on RRF for 650kHz selection.
They need to check switching frequency in the case of 820kΩ. (650kHz or not)
Best regards,
Satoshi
