LM2852YMXAX-3.3 is a type of DC-DC switching regulator available in several different configurations. As a part of the PMIC (Power Management Integrated Circuit) family, it is used to provide a stable power supply to a wide range of applications. This article provides an overview of the product, including its relevant application fields, main features and working principle.

Application Fields

The LM2852YMXAX-3.3 is particularly suitable for powering RFID (Radio-Frequency Identification) devices, low-power communication systems, and digital logic or embedded computing devices. It can also be used to supply power to optical-based systems, as well as other types of industrial or automotive devices requiring a constant, low current supply. Additionally, it is well-suited for portable gadgets such as tablets, laptops and cell phones.

Main Features

The LM2852YMXAX-3.3 is a synchronous switching regulator, meaning that it uses a switch as part of its internal circuitry to control the output voltage. It has a wide range of input voltages, with an operating range of up to 7.5V to 36V. This makes it highly versatile and suitable for a wide variety of applications. The unit also has a fast transient response, allowing it to quickly adapt to changes in external load conditions. Additionally, the LM2852YMXAX-3.3 is highly efficient, with a maximum efficiency of 96%.

Working Principle

The LM2852YMXAX-3.3 works by converting the input voltage to an output voltage through the use of an internal switch. When the input voltage is higher than the desired output voltage, the switch is opened and current passes through the output. Conversely, when the input voltage is lower than the desired output voltage, the switch is closed and current is prevented from flowing. This process is repeated at a high frequency, allowing the output voltage to remain at the desired level.

The LM2852YMXAX-3.3 also employs several other features to ensure a high level of performance. These features include over- or under-voltage protection, thermal shut-down protection, short-circuit protection and current limiting. Additionally, the device can be programmed to provide a range of output voltages, depending on the application requirements.

The LM2852YMXAX-3.3 is a high-performance, versatile DC-DC switching regulator that can be employed in a wide range of different applications. Thanks to its features, such as its high efficiency and wide input voltage range, it is well-suited for powering RFID and other low-power devices. Additionally, its advanced protection features provide additional protection against unwanted current or voltage fluctuations.
