..... The PWM chip Timing Ramp does not like to be loaded. Be very careful in trying to take a sample of the timing ramp for use as the compensation ramp in current-mode control. Even a very high impedance (100 k in some cases) can interfere with the clock operation. ..... Это справедливо для любого RС генератора.
