Ricoh R1286K Series 2ch DCDC Converter Datasheet
The Ricoh R1286K is a 2-channel DC/DC converter designed specifically for AMOLED display power sources. It integrates a step-up DC/DC converter and an inverting DC/DC converter into a single package. The step-up channel generates a selectable output voltage between 4.6V and 5.8V, while the inverting channel produces a negative voltage ranging from -2.0V to -6.0V, which is dynamically adjustable via a single-wire interface signal.
