The BD95850F-LBE2 is a DC/DC converter with a wide range of application fields, including automotive power systems, PCs, notebooks and industrial power solutions. It provides multiple functionalities, such as voltage monitoring and regulation, active-reset circuit programming, over-current protection, etc. The working principle of the BD95850F-LBE2 is based on the pulse-width modulation (PWM) control.

The BD95850F-LBE2 provides several advantages over traditional linear regulators. PWM offers higher efficiency compared to linear regulators, since the power is only dissipated for a short and limited time. Additionally, PWM allows for a wide range of operating frequencies, ensuring better flexibility and better dynamic response. Furthermore, the PWM control also allows for the implementation of advanced feedback systems to regulate the output voltage more precisely.

The BD95850F-LBE2 is based on a highly integrated power management system (PMIC). It includes a dual-channel buck converter that can support up to 3A current; a bipolar active-reset circuit that can be programmed to detect and reset against the over-current and the over-voltage conditions; and a built-in over-temperature protection. The dual-channel buck converters are used to generate fixed voltages with different currents, providing the power required by the load. The active-reset circuit can be programmed to determine when the total current or voltage output is reached, and it will automatically reset when the threshold is exceeded. This prevents damage to the components under abnormal conditions.

The BD95850F-LBE2 is able to achieve high efficiency with small form factor. Its buck converters provide a wide input voltage range, from 4.5V to 17V. Its active-reset circuit can be used to detect the output voltages and currents, and it can switch the voltage automatically according to the needs. The built-in over-temperature protection helps to protect the device against temperatures exceeding normal levels, further improving reliability and reducing the risk of device failure.

In conclusion, the BD95850F-LBE2 is a highly integrated DC/DC converter with numerous advantages, including high efficiency, small form factor, wide input voltage range, and advanced feedback systems. It is well-suited for applications in automotive, industrial and consumer electronics power systems. The built-in over-temperature protection and the active-reset circuit make it an ideal choice for reliable, stable power management.
