CXLC8961是一款用于有源矩阵有机发光二极管(AMOLED)面板供电的芯片。其内部集成了一个升压转换器和一个负压转换器，非常适合用于由电池供电的电子设备。高精度高效率的升压转换器内部集成了0.5Ω的NMOS功率管和0.6Ω的PMOS功率管，带载能力达250mA，1.4MHz的工作频率允许采用较小的电感。升压转换器采用同步整流技术并具有真关断功能，内部数字软启动控制浪涌电流。其输出可通过外部反馈电阻调节为4V~8V。高精度的负压转换器内部集成了0.4Ω的NMOS功率管和0.5Ω的PMOS功率管，带载能力达250mA，1.4MHz的工作频率允许采用较小的电感。输出范围-6V~-1V，外部可调。效率可达80%以上，内部数字软启动控制浪涌电流。CXLC8961采用12引脚的小型TDFN封装(3mm x 3mm x 0.6mm)。工作温度范围-40oC to +85oC。The CXLC8961 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 CXLC8961 is available in a small (3mm× 3mm× 0.6mm) 12 pin thin TDFN package and operates over the -40oC to +85oC temperature range.
