It generates a fixed 4.6 V positive rail and a programmable negative rail adjustable from -1.4 V down to -4.4 V — the two voltages an AMOLED panel needs for source-driver and gate-driver bias. Input range of 2.9 V to 4.5 V covers a single-cell Li-ion battery across its discharge curve, so the part can run directly off the battery without a pre-regulator in portable AMOLED applications. ## Package and footprint — 10-WFDFN with exposed pad The small footprint suits space-constrained display driver boards. Cut Tape works for prototype or low-volume builds. That means no forced redesign for AMOLED display power sections using this part.","metaTitle":"TPS65631WDSKR AMOLED Display Power Converter, Dual Output","metaDescription":"TI TPS65631WDSKR dual-output converter for AMOLED displays: 4.6V positive, -1.4V to -4.4V negative.
