BM2P051

PMIC - AC DC Converters, Offline Switchers

The BM2P051 Application Field and Working Principle is a small, integrated AC-DC converter and offline switcher designed for use in desktop and notebook PCs, as well as industrial applications. The device provides a compact, low-cost solution for many applications requiring a reliable, high efficiency, and low-noise AC-DC converter. The BM2P051 also features a low standby power consumption, high input voltage range, and wide output voltage range.

The BM2P051 includes an integrated switch-mode rectifier, AC input filter, and an offline switcher that incorporates both a linear controller and an adjustable constant-current overvoltage protection (OCP) circuit. The device provides excellent immunity to conducted and radiated interference sources such as power line spikes, power switches, and EMI/RFI sources. The device is also capable of operating in temperatures up to 95 degrees Celsius.

In terms of its working principle, the BM2P051 is a two-stage converter that uses two voltage converters, a rectifier and an AC-DC converter, in order to produce the desired output voltage. A linear controller with an adjustable voltage sense resistor is used to adjust the output voltage of the rectifier, which is then amplified and transferred to the output of the converter by an additional switching regulator. This output is then used to drive the AC-DC converter, which then regulates the output voltage for a better load regulation.

The BM2P051 features a wide range of protection features, including over voltage protection (OVP), over current protection (OCP), and over temperature protection (OTP). All protection functions are controlled by a logic circuit that is capable of detecting fault conditions such as open circuits, short circuits, excessive load currents, and high temperatures. If a fault condition is detected, the BM2P051 will cease operation and will alert the user of the problem.

The BM2P051 is an ideal AC-DC converter and offline switcher system solution for industrial, medical, and consumer electronics applications. Its high efficiency, small size, low cost, and reliable performance make it an excellent device for applications where traditional power supplies are too costly or inconvenient.

Whether you are looking to use the BM2P051 for industrial or consumer applications, its versatile design and intuitive operating characteristics make it the perfect choice for a wide range of applications. With its low standby power consumption, wide input voltage range, and stability robustness, the BM2P051 is an ideal choice for a wide array of AC-DC conversion and offline switcher applications.
