BD70HA3WEFJ-E2 Application Fields

BD70HA3WEFJ-E2 are commonly used in applications, such as instrumentation, digital systems, and medical equipment, which require very precise and low-noise voltage regulation. It is specifically designed for voltage regulation of DC/DC converters. The device is especially suitable for high-side switch-mode power supplies with up to ± 0.5% accuracy.

Additionally, this product has a high transient response that enables the power supply to meet the rapid load changes of modern systems. This device can also be employed in other strictly regulated and low-noise applications such as industrial automation, automotive, and aerospace.

BD70HA3WEFJ-E2 Working Principle

The working principle of BD70HA3WEFJ-E2 is based on a Voltage Regulation Ratio (VRR) of VOUT/VSENSE that is maintained within a predetermined accuracy range. These converters use an internal variable reference voltage uVref to provide an output voltage controlled by the a feedback loop. The output voltage is set by a potentiometer and the device is optimized to provide a high dynamic behavior.

The converter features over-temperature protection and current limiting with soft start capabilities. The device is provided with an internal thermal shutdown circuit, which prevents over-temperature issues on the power supply potentially caused by the continuous operation in elevated ambient temperatures with low short-circuit currents.

The BD70HA3WEFJ-E2 may also be used in adjustable mode. This mode permits an output voltage that is adjusted within the predefined range of the device. The output voltage is adjusted with the help of an external resistor. This feature is often employed in adjustable DC power supply applications.

Conclusion

BD70HA3WEFJ-E2 is an adjustable voltage linear regulator converter, primarily used for voltage regulation applications in instrumentation, digital systems, and medical equipments, as well as many other areas. Its working principle is based on a Voltage Regulation Ratio (VRR) of VOUT/VSENSE, and is equipped with features such as over-temperature protection, current limiting with soft start capabilities and an internal thermal shutdown circuit. This product offers excellent operational safety and stability and can be used either as a fixed or adjustable power supply.
