TPS63020-Q1: Some questions about using TPS63020 as a TEC driver
Part Number: TPS63020-Q1 I use TPS63020 as a TEC drvier。 I use the Equations in the article SLVA677 to calculate the value of the R1，R2 and R3 。 I want to understand the relationship between the TEC current and the frequency, amplitude and duty cycle of the Vcrtl.
Hi user6222316, Thanks for reaching out. First you need to see how Vctrl changes the output voltage. You can find this in several application notes, for example: <secret URL>/blogs_/b/powerhouse/archive/2020/02/18/adjusting-vout-in-usb-type-c-and-wireless-charging-applications-part-2 <secret URL>/lit/an/slyt777/slyt777.pdf The TEC current is then simply (Vin-Vout)/Rtec. Best regards, Milos
thanks，:-)
