Here is the datasheet of the TI switcher using in my design http://www.ti.com/lit/ds/symlink/tps54620.pdf
Could you please help to find the full-form of RT in RT resistor?
Attached is the relevant screenshot for reference.
Thanks VT

RT means resistor timer for an Astable Clock with external R or external logic clock for synchronous operation, possibly used for N phase shifted parallel converters or EMI or inductor property purposes.

\$\begingroup\$ So is it like, it has some definite C inside the chip and as the external R varies, the value of RC varies which causes the clock generation? \$\endgroup\$ Commented Aug 25, 2016 at 18:35

\$\begingroup\$ yes, thats what the spec says for R values. We know it also has some PLL but this would not be the VCO input hence the R bias or over-ride or RT/CLK input. \$\endgroup\$– D.A.S.Commented Aug 25, 2016 at 18:38

\$\begingroup\$ So my concept guess was correct but never knew the name. \$\endgroup\$ Commented Aug 25, 2016 at 18:40

\$\begingroup\$ I too, guessed, with this understanding. \$\endgroup\$– D.A.S.Commented Aug 25, 2016 at 18:42

Assuming that "the full-form of RT" means that you want to determine the value of RT, read Section 8.4.1.
