RT4720A
Triple DC/DC Boost Converter for AMOLED
General Description
RT4720A is a triple channels DC/DC converter which is designed to provide the power of AMOLED.
It integrates step up DC/DC and an inverting converter to provide the positive and negative output
voltage required by AMOLED.
For the portable application, board space and efficiency are always major concerns.
The high switching frequency of RT4720A allows the use of low inductance inductor to save the board space.
It provides dual positive output
voltage, one is a fixed 5.
8V or 7.
7V output
voltage by SEL pin and the other positive output is fixed 4.
6V.
For the negative output
voltage, it can be programmed by external MCU throug...
