The BM1051F-GE2 IC is a three-section, step-down regulator module for the PMIC (power management integrated circuit) market that consists of two DC-DC converters, an offline switcher, and a pulse width modulation (PWM) controller. The controller is used to provide power conversion from a high voltage source to a low voltage levels suitable for microcontroller and other digital stuffs. The module also includes several protection functions such as power-sequence protection and over-temperature protection.

The BM1051F-GE2 IC is an ideal choice for LED drivers, power supply systems, and high wattage chargers. It is a three-terminal regulator with adjustable output voltage ranging from 0.7V to 5.5V. The IC provides excellent efficiency via a synchronous rectifier and a PWM controller. The PWM controller canuoutput f equal to 50% to 97%.

Using two integrated DC-DC converters, the BM1051F-GE2 IC can replace two dedicated high frequency controllers. This provides improved power efficiency and reduces the number of external components required. The IC is also equipped with a protection against multiple faults such as over-current and over-voltage shutdown. It integrates an integrated current sense circuit that helps in storing the overload current information.

The BM1051F-GE2 IC is designed to operate from DC input voltage sources. Its operating frequency is 44-55kHz and operates from an input voltage range of 4.0V to 18V. The switching current capability is programmable up to 10A, and its peak current is up to 30A. The IC features robust self-protection features like over-temperature protection, to prevent the IC from being damaged due to excessive heat. It also has short-circuit protection, which shuts down the switch if the output current reaches a dangerous level.

The BM1051F-GE2 IC features good EMI performance and is compatible with international standards like the EN61000-3-2, EN61000-3-3, EN61000-4-2, and EN61000-4-3, among others. It uses an internal soft-start circuit, which reduces the inrush current and prevents excessive stress on the power supply. It also has a low-noise operation that makes it suitable for embedded, industrial, and medical applications.

In conclusion, the BM1051F-GE2 IC is a high performance three-section, step-down regulator module for PMIC market. It is designed for high wattage chargers, power supplies, and LED drivers and offers the advantage of synchronous rectifier and PWM controller. The IC features an adjustable output voltage range, over-current protection, and short-circuit protection. The BM1051F-GE2 IC has robust self-protection features and excellent EMI as well as low-noise operation makes it an ideal choice for embedded, industrial and medical applications.
