DVM (Dynamic Voltage Management). To minimize the over-/undershoot during a change of the output voltage, the DVM can be enabled.
With DVM the output voltage will ramp up/down with a selectable slope after the new value was written to the registers. Without DVM the slew
rate of the output voltage is only determined by external components like the coil and load capacitor as well as the load current.
Fast Regulation Mode. This mode can be used to react faster on sudden load changes and thus minimize the over-/undershoot of the output
voltage. FRM needs an 22uF output capacitor instead the 10uF one to guarantee the stability of the regulator.
Low Frequency Operation. Especially for very low load conditions, e.g. during a sleep mode of a processor, the switching frequency can be
reduced to achieve a higher efficiency.
100% PMOS ON Mode for Low Dropout Regulation. For low input to output voltage difference the DCDC converter can use 100% duty
cycle for the PMOS transistor, which is than in LDO mode.
