Introduction
The BD10IC0MEFJ-ME2 is a two-channel integrated linear voltage regulator from ROHM Semiconductor. It has been designed to work as an internal power supply for Digital Consumer applications with HDMI 1.4, such as OLED displays, HD TV receivers, Digital Audio & Video Players, and Home Theatre Systems. The voltage regulator is suitable for situations where there is little room for a power supply, or when multiple power supply appliances are connected to a single point of power, as in the case of digital consumer products. It also supports other digital consumer products such as digital sign boards and car video equipment.

Application Field
The BD10IC0MEFJ-ME2 is designed for digital consumer applications with HDMI 1.4 as its main application field. Its minimum/maximum voltage range of 0.3V-4.4V and output current range of up to 8A make it ideally suited for applications that require multiple power supply appliances to be connected, such as in digital sign boards dual-channel OLED displays and HDTV receivers. Similarly, due to its wide input Voltage range of 5V to 20V, including the support of various low-voltage railsapplications, it is particularly suitable for applications in situations where there is a significant power requirement and little room for a typical power supply.

Working Principle
The BD10IC0MEFJ-ME2 has a simple but effective internal circuit architecture and operation. It consists of an on-chip voltage regulator and a low-voltage regulator and a control logic. The voltage regulator is based on a P-channel MOSFET switch which is controlled by the logic that is connected to the voltage regulator and is powered from the external Vcc supply.The voltage regulator has two input pins, one for the external Vcc power supply and the other for the low-voltage regulation. The low-voltage regulator regulates the voltage to be supplied to the output. It consists of an oscillator, a power stage with MOSFETs, which are used as a switch to regulate the output voltage, and a digital compensation circuit. The voltage regulator can be supplied also by the low-voltage regulator by changing the control logic. The output voltage is monitored by the internal circuit and it is able to automatically switch the output voltage between internal Vcc and the low-voltage range. The output voltage is also adjustable by setting the control logic.

Conclusion
The BD10IC0MEFJ-ME2 is an integrated linear voltage regulator from ROHM Semiconductor. It is designed to work as an internal power supply for digital consumer applications with HDMI 1.4, such as OLED displays, HD TV receivers, Digital Audio & Video Players and Home Theatre Systems. The voltage regulator is suitable for situations where there is little room for a power supply, or when multiple power supply appliances are connected to a single point of power, as in the case of digital consumer products. It supports other digital consumer products such as digital sign boards and car video equipment. The voltage regulator provides a range of 0.3V-4.4V and output current of up to 8A. Its simple but effective internal circuit architecture and operation make it an ideal choice for applications with significant power requirements and little room for a power supply.
