Pin Number Name Function 1 RAMP PWM modulator ramp. In voltage mode an external R−C circuit from Vin sets the PWM Ramp slope to implement feedforward. In current mode control, the resistor of the external R−C circuit connects to REF for ramp compensation 2 SS Soft−start control. A 20 μA current source charges the external capacitor connected to t.
