Product Description

The TCS3512 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-efficiency250mA output regulator. It features an internal 0.5N-MOSFET, 0.6 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 0.4 N-MOSFET, 0.5 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 TCS3512 is available in a small (3mm×3mm×0.6mm)12 pin thin TDFN package and operates over the -40ºC to +85ºC temperature range.
