RT4730 Triple Output AMOLED Bias Evaluation Board

Richtek’s evaluation board supports up to 50 mA of output current and is ideal for wearable AMOLED products

Image of Richtek USA Inc. RT4730 Triple Output AMOLED Bias Eval Board Richtek’s RT4730 is a highly integrated power solution with buck-boost and an inverting charge pump to generate positive and negative output voltage. The output voltages can be adjusted by Swire interface protocols. With an input voltage range of 2.9 V to 5.2 V, the RT4730 is optimized for products powered by single-cell batteries and symmetrical output currents up to 50 mA. The EVB_RT4730WSC evaluation board is designed to demonstrate the capabilities of the RT4730. The evaluation boards combine the RT4730 with external components to support up to 50 mA of output current.
