It delivers a fixed 4.6 V positive rail and a programmable negative rail adjustable from -1.4 V down to -4.4 V, covering the bias requirements of most small-to-medium AMOLED panels used in smartphones, wearables, and portable instruments. The input voltage range of 2.9 V to 4.5 V is directly compatible with a single-cell Li-ion battery, so the part fits designs where the display bias must be generated from the system battery without an intermediate boost stage. ## What the two output rails mean for the AMOLED BOM AMOLED panels need a positive source voltage (typically 4.6 V) for the pixel-drive TFTs and a negative bias voltage (adjustable between -1.4 V and -4.4 V) for the cathode and gate-off drive. The TPS65631DPDR integrates both rails in one IC, saving the board area and inductor count that a discrete positive-plus-negative converter pair would require. The negative output is adjustable — a resistor divider sets the exact voltage within the -1.4 V to -4.4 V window, letting the designer tune the panel bias for optimal contrast and gate-off margin without changing the IC.","metaTitle":"TPS65631DPDR Dual-Output AMOLED Display Power Converter","metaDescription":"Texas Instruments TPS65631DPDR dual-output converter for AMOLED displays.
