Hello,
I'm using TPS92210 for LED lighting that Topology is Buck converter.
Also used PMP3672 Reference designs schematic. (http://www.ti.com/lit/df/slvr948/slvr948.pdf)
input voltage is unversal(both low line and high line, 90~240Vac), Output current is 450mA.
in case of flyback type,
I have found the caluration formula by xls(sluc242.zip)
But in case of buck converter,
I couldn't find the calulation formula!!
I have to set the exact values of the Inductor and others main R/C components.
1) inductor matching inductance value?
2) peripherals R/C components matching values?
If have the TPS92210 buck design Tool?
Could you please let me know how to calulate the main components?
thanks,
eric
