BD9E103FJ-E2 Integrated Circuits (ICs)

BD9E103FJ-E2 application field and working principle

As part of the PMIC (Power Management Integrated Circuit) family, BD9E103FJ-E2 is a DC DC Switching Regulator that is a robust power solution applicable to a wide range of industrial, automotive, and consumer applications. It is a high-performance, high-efficiency switch mode regulator capable of providing up to 5A output current.

The BD9E103FJ-E2 DC DC Switching Regulator is mainly applied to derive an adjustable output voltage from an input voltage as low as 4.5V to as high as 32V. The adjustable output voltage range is from 0.9V to 18V. It features a constant switching frequency up to 300KHz, which provides improved noise reduction and a smaller size solution compared to linear regulators.

The BD9E103FJ-E2 DC DC Switching Regulator offers a wide adjustable output voltage range and high output current, as well as a wide input voltage range. It is also very efficient and thermally efficient, with an efficiency of more than 95%.

The BD9E103FJ-E2 DC DC Switching Regulator works on the principle of constant switching frequency. It use an internal oscillator to generate a frequency signal and drives the main power switch according to the frequency signal. The output of the regulator is determined by the duty cycle of the on/off period of the main power switch. When the output voltage is higher than expected, the duty cycle of the main power switch will be reduced to get the expected output voltage. On the contrary, when the output voltage is lower than expected, the duty cycle will be increased.

The BD9E103FJ-E2 DC DC Switching Regulator features fixed and adjustable switching frequency, current limit protection, soft start, and low-ripple noise. It also has over-voltage and short-circuit protection to guarantee the best power performance in all kinds of application scenarios. Its built-in bias PWM control circuit maximizes efficiency in all operating conditions.

In conclusion, the BD9E103FJ-E2 DC DC Switching Regulator is a high-performance and high-efficiency integrated power solution, ideal for a variety of applications. Its wide adjustable output voltage range, high output current, wide input voltage range, and high efficiency offers the user reliable and robust power performance.
