I'm checking the TIDA-00318: http://www.ti.com/tool/TIDA-00318. Because I'm trying to change the coil for either the WR221230-36M8-G (https://product.tdk.com/info/en/catalog/datasheets/wlc_rx_wr221230-36m8-g_en.pdf) or the WR111180-45F5G (https://media.digikey.com/pdf/Data%20Sheets/TDK%20PDFs/WR111180-49F5-G_Spec.pdf).
And so, I'm super confused because if I use this formula from the bq51003 datasheet for the coil (https://product.tdk.com/info/en/catalog/datasheets/wlc_rx_wr222230-26m8-g_en.pdf )TI used during the TIDA-00318 (http://www.ti.com/tool/TIDA-00318 ) testing:
I get that C1 = (100KHz*2pi)^2*27uH]^(-1) = 93.8nF and C2 = (1MHz*2pi)^2*27uH - 1/(93.8nF)]^(-1) 0.948nF. Which is different from the values TI has fixed in the schematics for Altium:
Can someone tell me if I'm forgetting steps or if they used a different coil for this schematic or if it is just that I'm doing my calculus in the wrong way??
