Maximum output voltage difference between PWM control sw reg and D-CAP/DCS

I'd like to know the reason why the maximum output voltage of DCAP series or DCS Control Sw reg

are lower than that of common PWM Sw reg?

For example, the maximum input voltage of these 3 parts are same, but the max output voltage are different.

Where does the difference come from? 

TPS62148: 12Vout max(DCS Control)

TPS562207S: 7Vout max(DCAP-2)

TPS62110: 16Vout max( PWM Voltage mode)
