Active production — AMOLED display power IC
Texas Instruments TPS65632ARTER is an active-production PMIC for AMOLED displays, delivering three regulated outputs from a 2.9V to 4.5V input rail. The three outputs are 4.6V, 7.7V, and a programmable negative rail from -1.4V to -5.4V — the negative supply is the one that typically drives the OLED cathode bias and must be set within the display panel's specification.
Output rails and operating range
The positive rails (4.6V and 7.7V) are fixed; the negative rail is adjustable via external resistors across a -1.4V to -5.4V range.
The part is ROHS3 compliant.
