Push-Pull Outputs (Continued) PWM Comparator The PWM comparator compares the slope compensated current ramp signal to the loop error voltage from the internal error amplifier (COMP pin). This comparator is optimized for speed in order to achieve minimum controllable duty ...
Page 12
Slope Compensation The PWM comparator compares the current sense signal to the voltage at the COMP pin. The output stage of the internal error amplifier generally drives the COMP pin. At duty cycles greater than 50 percent, current mode control ...
