The LM34925MR/NOPB is an Integrated Circuit (IC) that falls under the Power Management Integrated Circuit (PMIC) Voltage Regulators - DC DC Switching Regulators category. It is designed to help reduce board space and save the time of designing a complex multiple power supply reference design. Its internal tri-state controller and high-side MOSFET enable a high-efficiency, low-cost, low-noise, current mode flyback switched mode power supply (SMPS) solution. This IC works with a frequency modulated (FM), and is intended for industrial applications.The IC is an integrated package and has a typical power temperature coefficient of 0.005%. It offers a wide operating frequency range, making it an ideal choice for a wide variety of applications where a regulated output is either required or desired, such as for DC-DC conversion, for communication systems, for power electronics, for audio amplifiers and music equipment, for computer peripherals, for wireless communications, and for any other electronic device where a low noise, efficient voltage regulation is needed.The LM34925MR/NOPB provides a multiple mode control with a flexible selection of operating frequency, making it suitable for a large variety of applications. The device also works with a wide input voltage range (16 to 25V) and provides an adjustable output voltage range of 2.3V small signal (VSS) to 5.5V high signal (VHS). The device includes adjustable peak current feedback loop, as well as over-voltage and over-current protection.It has multiple operating modes. The most common is the PWM mode. In this mode, the device operates at a fixed frequency and switching is performed by a variable duty cycle. This mode is suitable for applications with relatively low power changes in the load such as office equipment and communication equipment. Another common mode is the pulse frequency modulation (PFM) mode. This mode provides high efficiency while reducing noise because higher frequencies are used. It is suitable for applications with high power changes in the load such as motor drives and power supplies.The LM34925MR/NOPB also works with an integrated current-mode feedback loop, making it an attractive solution for high-current applications. The IC also has internal thermal protection, making it an efficient, cost-effective and highly reliable solution for a variety of applications.In conclusion, the LM34925MR/NOPB is an integrated circuit for high-quality DC-DC conversion and voltage regulation. It enables high efficiency, low noise, and includes protection against current overload. Its adjustable peak current feedback and multiple operating modes make it a suitable choice for a variety of applications, including office equipment, communication equipment, audio amplifiers and music equipment, computer peripherals, wireless communication, and power electronics.
