It operates using D-CAP2™ mode control. The fast transient response of D-CAP2™ control reduces the output capacitance required to meet a specific level of performance. Proprietary internal circuitry allows the use of low ESR output capacitors including ceramic and special polymer types. 8.2 Functional Block Diagram 8.3 Feature Description 8.3.1 Soft Start And Pre-Biased Soft Start The soft start function is adjustable. When the EN terminal becomes high, 6 μA current begins charging the capacitor which is connected from the SS terminal to GND. Smooth control of the output voltage is maintained during start up. The equation for the slow start time is shown in Equation 1. VFB voltage is 0.765 V and SS terminal source current is 6 μA.
