Gerneral semiconductor manufacturers OEMs, such as Shindengen, integrate voltage regulators and DC-DC converters in power management ICs (PMIC) to control the supply and monitor their performance. The LV5747QA-NH from Mitsubishi is such a solution. This power management IC integrates a voltage regulator and a DC-DC switching controller, providing an effective solution for those applications requiring a 3-2.5V single power supply design. The LV5747QA-NH is capable of achieving high conversion efficiency, making it suitable for powering a wide range of electronic devices, from motor control systems and automotive infotainment systems to handheld communication devices.The LV5747QA-NH integrates a voltage regulator and a DC-DC conversion controller on the same chip, simplifying the power supply design. The voltage regulator integrated in the chip operates based on the voltage drop across a P-channel MOSFET (PMOS), providing a regulated output up to 3V. The DC-DC controller integrated into the device enables the design of a dipole-based switch mode DC-DC converter with an input voltage range of 3-2.5V. The supply voltage adjustment range is extended and the output current limit is improved.The LV5747QA-NH combines the voltage regulator and switching controller components into one package, making it a cost-effective solution for a wide range of applications. The device includes several functions such as overload protection, current limit protection and thermal overload protection. The overload protection monitors the input voltage and shuts down the device in the event of an overload. The current limit protection limits the output current to a safe level and the thermal overload protection reduces heat generated.In conclusion, the LV5747QA-NH is a highly cost-effective solution for a wide range of applications. The voltage regulator and DC-DC conversion controller are integrated into one package, providing high efficiency and performance. The device offers several additional protection mechanisms to ensure the safe operation of the device and other devices connected to it. The LV5747QA-NH is a great solution for those applications requiring a 3-2.5V single power supply design.
