Power management has become an invaluable factor in modern electronics, which forms a basic point of reference in the development of any new system in a variety of different applications. This ranges from very low-power technological systems with numerous sensors, to high-power equipment and large-scale systems.

The BD3504FVM-TR belongs to a family of voltage regulators and linear regulator controllers which are essential for managing power for a given device. This article will outline the application field and working principles of BD3504FVM-TR and explain the crucial role it can play in the development of new products.

What is the BD3504FVM-TR?

The BD3504FVM-TR is a programmable current-mode pulse width modulation (PWM) control system with on-chip protection and temperature compensation. It is intended to be integrated into high-performance and low power conversion applications such as buck regulator systems, DC-DC converters, as well as in applications such as voltage mode control systems.

The BD3504FVM-TR is a 4-channel pulse width modulator featuring a high-precision, 2.0V internal reference voltage, adjustable overcurrent protection and adjustable over-temperature protection. This allows easy implementation of the overall system protection.

Application Field

The BD3504FVM-TR is ideal for use in high-performance, high-efficiency, low-power conversion applications such as DC/DC converters, spanning from sub-1A applications up to 10A applications. It can accurately control the duty cycle of the output and ensure a stable output voltage. Additionally, it provides protection against both overcurrent and over-temperature conditions, further improving the performance of your system.

Working Principle

The BD3504FVM-TR consists of a dedicated PWM comparator and four independent PWM outputs. By sensing the input voltage and current, the PWM comparator generates a pulse width modulation signal with a wide range of duty cycles. The four PWM outputs are independent, allowing the user to control multiple loads simultaneously. This operation allows for multiple protection features such as overload, over-temperature protection and voltage monitoring.

The on-chip protection features such as over current and over-temperature protection help provide a more reliable and durable system. Additionally, the adjustable over current protection limit ensures reliable operation under harsh conditions. In the case of an overload, the comparator will reduce the duty cycle until the load is within the set limit.

Conclusion

The BD3504FVM-TR is an excellent choice for the development of high-performance, low-power conversion applications such as DC/DC converters. It provides precise and robust control over the output voltage while providing a range of protection features, such as overcurrent and over-temperature protection. This makes it ideal for a wide range of applications that require precise, reliable and cost-effective voltage regulation.
