LM2852XMXA-1.0

The LM2852XMXA-1.0 is a switching regulator integrated circuit (IC) chip designed by Texas Instruments. It is an On-Board FET Switch with 28V Input Voltage, maximum output current of 2A, integrated Synchronous Rectifier, and adjustable output voltage in the range of 0.8V to 5.5V. This IC also has built-in features such as power-good indicator, programmable soft-start, and adjustable current limit. In terms of form factor, LM2852XMXA-1.0 measures 8.2mm x 9.7mm and is offered in an Exposed Pad (EP) QFN-20 package.

LM2852XMXA-1.0 is a perfect fit for applications requiring a tightly regulated output voltage such as miniature motors, cameras and medical equipment where an adjustable voltage range of 0.8V to 5.5V is required. As a switching DC-DC regulator, this versatile IC also provides high efficiency and low noise, making it suitable for VRM (Voltage Regulation Module) and industrial battery applications.

The working principle of LM2852XMXA-1.0 is fairly straightforward. When the input voltage rises above the programmed output voltage, the chip will open the FET switch, connect the output voltage to the input voltage source, regulate the output voltage, and then turn off the FET switch. This repeating cycle ensures that the FET switch will provide a steady output voltage to the load. LM2852XMXA-1.0 also has additional features of adjustable current limit protection and over-temperature protection, which helps protect the IC from various power related faults.

In summary, LM2852XMXA-1.0 is a versatile DC-DC switching regulator IC chip with excellent performance and a wide range of applications. It is specifically designed for miniature motors, cameras, medical equipment, and industrial battery applications, providing a tightly regulated output voltage. The built-in features also help protect the chip from power related faults and enhance the performance of the IC. Thus, it is an ideal choice for applications that require high efficiency, low noise, and adjustable output voltage.
