BD63536FJ-E2 Voltage Regulated DC DC Switching Controllers

The BD63536FJ-E2 is a voltage regulated DC DC switching controller from the ROHM Semiconductor company. This device is part of the PMIC (Power Management IC) family, specifically within the Voltage Regulator and DC DC Switching Controller categories. Its purpose is to provide a regulated supply of electricity from the input line DC power sources, such as batteries and AC adapters, to the load (e.g. computer or phone). This makes it suitable for a variety of applications, such as consumer electronics, industrial, and automotive.

The BD63536FJ-E2 is programmed to output a fixed voltage of 1.5V or 3.3V. It has an input voltage range of 4.5V to 32V, making it capable of handling a wide variety of input sources. It also offers maximum output current of 1A, making it suitable for applications which require higher output current. Additionally, it features over current, over voltage, and under voltage protection.

The operating temperature range of this voltage regulated DC DC switching controller is -40 to 85 degree Celsius, allowing to be used in a variety of environments. It is available in a PQFN-12 package with bottom-side pads for dissipating heat and good thermal heat dissipation. Furthermore, it is designed to work efficiently at low switching frequencies, which can help reduce EMI noise generation.

Working Principle

The working principle of the BD63536FJ-E2 voltage regulated DC DC switching controller is based on a "PWM" (pulse width modulation) control method. When the output current reaches a certain level, the controller compares the input voltage and the load voltage and adjusts the duty cycle of the PWM signal accordingly. The duty cycle is the ratio of the on time to the total cycle time of the current. As the duty cycle increases, the output voltage increases. The BD63536FJ-E2 keeps the output voltage within a specified range by constantly adjusting the duty cycle as the input voltage and load current change.

Protection Features

The BD63536FJ-E2 not only provides voltage regulated voltage but also has a variety of protection features. It offers over current protection, which protects the device and the application from any dangerous current surges caused by a faulty load or other situations. Additionally, it provides over voltage and under voltage protection, which prevents the output voltage from exceeding a certain limit or dropping below a predetermined level.

Conclusion

The BD63536FJ-E2 voltage regulated DC DC switching controller is a handy device that can provide reliable and regulated voltage output from input DC power sources. Its adjustable duty cycle make it suitable for a variety of applications and its wide input voltage range allows it to handle a variety of input power sources. Furthermore, it offers several protection features, such as over current, over voltage, and under voltage protection, for added security and reliability. Its small size, high efficiency, and excellent thermal performance make it an ideal choice for a variety of applications.
