Hello,
Page 26 (PMP4026 Schematic) of the following features the output sense resistor voltage being divided down by R5 & R3. This seems like a bad idea..do you agree?
Also, why are they using a 2Ohm sense resistor with 700mA of current?..surely too much dissipation, considering that the error amp ref voltage is just 200mV in the TPS40211..
**broken link removed**
..also, what is Q11 for...its just a nfet turned off?
Also, on page 28 of the above (schem PMP3943) surely R5 should be 49.9k and not 49.9?
