The BD9120HFN-TR is an automotive-compliant package product in the BDR family of DC-DC switching regulators. It is used for applications that require a high current capacity in a compact package, such as automotive power management and general power supply. This chip is a high current DC-DC neddling regulator, and can deliver up to 24A peak current.

The BD9120HFN-TR offers a wide input voltage range of 4.5V to 21V, and can output a range of voltages from 0.8V to 17V. It has a wide assortment of features designed to improve system reliability and efficiency, including over-temperature protection, over-current protection, power-good detect, wide adjustability, and soft-start function. It also features an additional control device that can control the output voltage via an external control pin.

This device is capable of a switching frequency of 1.6MHz, allowing for higher output voltages and decreased output ripple. It employs an adaptive constant-on-time control scheme that enables fast dynamic response. This chip also provides constant on/off switching to minimize EMI, as well as a low start-up current which helps reduce the noise of the system.

The BD9120HFN-TR is a monolithic integrated circuit fabricated with N-channel MOSFETs and Schottky diodes, making it suitable for space-restricted applications, including automotive and portable electronics. It is designed to support an input voltage of up to 21V and a maximum output current of 24A, offering high efficiency power conversion and greater power capability than other DC-DC converters.

This chip features a high level of protection with over-current and over-temperature protections, allowing it to shut down when an over-current or over-temperature event is detected. A power-good detect pin is also offered, which can be used to monitor the output voltage accuracy. The BD9120HFN-TR also offers an externally adjustable operating frequency, allowing users to optimize their system for optimum efficiency and performance.

Finally, the BD9120HFN-TR also offers numerous options for controlling the output voltage, such as an adjustable voltage set point, external pull-up resistor, and onboard adjustable resistor. This provides greater system flexbility depending on user requirements. Overall, this DC-DC switching regulator is an ideal solution for applications that require both high current capability and a compact package size.
