AI-generated Summary:
Output voltage above 1.9 V for DA9217/DA9220/DA9121/DA9122 is achieved by using external resistors and capacitors. These devices operate within an input voltage range of 2.5 V to 5.5 V and support configurable output voltage from 0.3 V to 1.9 V natively. By applying a resistive divider and recommended external components, the output voltage can be adjusted beyond 1.9 V. The document provides recommended component connections, waveform results, and register settings to realize this higher output voltage. It includes practical examples with input voltages of 3.7 V and 5 V, output voltages of 2 V and 3.3 V, and load currents of 3 A.
