Hi,
There is no further information on internal slope compensation and current sense in TPS54061 datasheet. What is the value of slope compensation ramp and current sense resistor/gain?
Thanks!

Hello Juha,
The ramp comp is approximatly 60% of rated current in a clock cycle = 120 mA(Peak PH current)*fsw for the TPS54061. This part uses the high side MOSFET as a sense resistor. When calculating loop response, the relavent specification is "COMP to Iswitch gm" which for the TPS54061 is 1 A(Peak PH current)/V(Comp voltage).
