| 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 | |
