14 D-CAP2™

A slight variation of D-CAP with the same transient and external component advantages as D-CAP. This control mode supports ceramic output capacitance without external circuitry. A signal from an internal ripple-injection circuit is fed directly into the comparator, thus reducing the need for output voltage ripple from the capacitor’s ESR. The ramp is emulated by the output inductor.

When to use: When desiring fast transient response with low-ESR ceramic output capacitors.
