EUP2512

EUP2512 Dual Channel DC-DC Converter for AMOLED DESCRIPTION The EUP2512 generates power supply rails for active-matrix organic light emitting diode (AMOLED) displays. It includes a step-up DC-DC and an inverting DC-DC converter making it suitable for battery operated products. The step-up converter is a high-accuracy power-efficiency 250mA output regulator. It features an internal 0.5Ω N-MOSFET, 0.6Ω P-MOSFET and 1.4MHz operation frequency allowing the use of small inductor and capacitors. The integrated synchronous rectifier allows the true shutdown of the outputs. An internal digital soft-start function controls inrush currents. The step-up converter output can be externally set 4V to 8V. The inverting converter is a high-accuracy 250mA regulator. It features an internal 0.4Ω N-MOSFET, 0.5Ω P-MOSFET and 1.4MHz operation frequency allowing the use of small inductor and capacitors. Its -6V to -1V output efficiency up to 80% at 150mA. An internal digital soft-start function controls inrush currents. The EUP2512 is available in a small (3mm × 3mm × 0.6mm) 12 pin thin TDFN package and operates over the -40ºC to +85ºC temperature range.
