Introduction

The power management integrated circuit (PMIC) LM2731YMFX is a DC-DC switching regulator that is an efficient and reliable source of voltage regulation. It serves to convert an input voltage between 2.5V and 24V into an output voltage of up to 24V. The LM2731YMFX is a high-lighting single-stage boost converter, operating with a switching frequency of 500kHz, improving efficiency, decreasing the size of the external components, and shortening time to market. It is used mainly in low voltage industrial applications, such as communications networks, POE cards, and other industrial applications. In addition, its features, including a wide input voltage range and wide output adjustable range, as well as its internationally-recognized safety certificates, make it popular for low power industrial applications.

Features

The LM2731YMFX features a wide input voltage range from 2.5V to 24V and an output voltage range from 0.8V to 24V. It also features adjustable output, enabling users to tune the regulators for different output voltages and current levels, meeting the needs of different applications. Additionally, the LM2731YMFX provides a low quiescent current of 30 uA and is highly efficient with up to 95%, enabling the regulator to remain cool to the touch even during heavy-duty operations.

The LM2731YMFX also includes a number of safety features that have enabled it to meet the stringent safety requirements of UL, CSA, and TUV. These safety features include overvoltage protection, undervoltage protection, over current protection, short circuit protection, and over temperature protection. These functions help protect the device and the connected components from damage due to incorrect operating conditions.

Application Field

TheLM2731YMFX is mainly used in low voltage industrial applications, such as communication networks, VoIP systems and digital multimedia. Its wide input voltage range allows it to be used in a variety of environments from industrial to commercial and residential applications. Its power saving function also makes it suitable for applications in remote or battery powered systems with limited source of power. In addition, the high efficiency and low standby current of the LM2731YMFX makes it ideal for use in applications where power and size are critical, such as laptop computers, handheld devices, medical equipment, and solar power systems.

The LM2731YMFX is also used in a variety of automotive systems, such as body control, lighting control, and power train systems. Its wide operating temperature range from -40°C to 85°C makes it an ideal choice for applications in the automobile industry. The LM2731YMFX also has an adjustable, pulse-width modulation (PWM) frequency, allowing users to customize their power system design.

Working Principle

The LM2731YMFX operates as a single-stage DC-DC boost converter. The converter starts by taking energy stored in an inductor and converting it into energy stored in an output capacitor. When the input voltage exceeds the output voltage, the switch turns on and transfers energy stored in the inductor to the output capacitor. When the input voltage drops below the output voltage, the switch turns off and the energy stored in the output capacitor is transferred back to the inductor.

The LM2731YMFX is an adjustable regulator, meaning the output voltage can be adjusted by changing the duty cycle of the PWM signal. The duty cycle is the ratio of the conduction time to the switching period. The higher the duty cycle, the higher the output voltage and the lower the duty cycle, the lower the output voltage. The LM2731YMFX also features over-current protection, in which a small current is limited to protect the output device from over-current conditions.

Conclusion

The LM2731YMFX is a high-lighting single stage boost converter that is well-suited for use in low voltage industrial applications. Its features, including a wide input voltage range, adjustable output, low quiescent current, high efficiency, and safety certificates, make it a reliable and efficient source of voltage regulation. Additionally, its applications in automotive systems, communication networks, VoIP systems, digital multimedia, remote or battery powered systems, and solar power systems, make it highly versatile and popular for industrial applications.
