PMIC - Voltage Regulators - Linear is a widely utilized type of regulators, which is effective in performing regulated operation of an intake voltage while still providing a permissible output voltage. The BD60HC0WEFJ-E2 is one of the most commonly used linear voltage regulator, and it applies to a wide range of applications and packages. This article will provide an overview of the BD60HC0WEFJ-E2 with a focus on its application fields and working principles.

Application Fields

The BD60HC0WEFJ-E2 can be applied in D2PAK and SOT-223 packages with variants for use in harsh, wide temperature range. It uses a linear voltage regulator, comprising of a P-channel MOSFET receiving PWM control and a current sense, enabling it to provide an adjustable voltage that is reliable and highly efficient. The output voltage range maxes out at 60V and is adjustable 0.24~60V and is based on the feedback voltage, which can be adjusted with external components.

The BD60HC0WEFJ-E2 is primarily used as a power supply in computers, servers, and notebooks. It is also widely used in power adapters, external power supplies, automotive power systems, and industrial control circuits. The product also includes a temperature protection feature to protect the output voltage of the system.

Working Principle

The BD60HC0WEFJ-E2 works based on the linear principle. It is composed of a P-channel MOSFET receiving PWM control, a current sense, and a voltage reference. It uses a voltage reference circuit to sense the output voltage of the system, and when it exceeds the set threshold, the P-channel MOSFET is triggered to stop the power transmission and protect the wiring from going beyond the safe level. The current sense is used to limit the current to the system, and when it reaches the maximum value, the P-channel MOSFET is triggered again to shut down the power transmission and protect the wiring. This whole process is called the voltage regulation and it is the key feature of a linear voltage regulator.

The BD60HC0WEFJ-E2 also adds the temperature protection feature, which is based on the thermal resistance of the chip. When the temperature reaches beyond a certain level, the thermal resistance will be triggered and the voltage will be reduced to reduce the internal power of the system and limit the damage caused by the high temperature. This feature makes the BD60HC0WEFJ-E2 especially efficient in heat dissipation, making it suitable for use in harsh, wide temperature range environments.

Conclusion

The BD60HC0WEFJ-E2 is a linear voltage regulator made of a P-channel MOSFET receiving PWM control, a current sense, and a voltage reference. It can provide adjustable voltage in a wide range of applications, such as computers, servers, notebooks, power adapters, external power supplies, automotive power systems, and industrial control circuits. Thanks to its temperature protection feature, it can work efficiently in a wide range of temperatures.
