The PMIC (Power Management Integrated Circuit) ubiquitous Voltage Regulators contain a number of related DC DC Switching Controllers, one of which is the BD9775FV-E2. It’s application pertains to the following; switching AC/DC or DC/DC converters, simple converters, SMPS (Surface-Mount Power Supplies), and high-current DC and AC switching equipment.

The BD9775FV-E2 is a voltage controller that is current-mode with switching frequencies of up to 500kHz. It has a wide 8V to 40V operating range for various power supplies applications. Its wide input voltage range makes it a versatile and reliable controller for many developers.

The main purpose of this controller is to accurately control an output voltage from a DC power source by using Pulse-Width Modulation (PWM) technique. It works by switching the output voltage from 0V to the voltage supplied from the DC power source. This is done by using special circuitry to detect the output voltage and adjust pulses width accordingly. Once the pulses widths are set by the circuitry, then the output voltage is precisely maintained. It can also be used for controlling output power levels as well.

The BD9775FV-E2 also has a high-speed switching capability, with switching frequencies extending up to 500kHz. This allows it to be used in high-performance designs. It is also able to provide a wide output voltage range from 0V to 50V. Furthermore, it has an ultra-low input to output delay time of just 1.1µs, which is suitable for many control applications.

This controller also comes with various other features that makes it suitable for many different applications. It has a typical on-resistance of 20mΩ and a total gate charge of 8nC, allowing it to provide high efficiency with fast switching frequencies. It also comes with a built-in over-temperature protection, short-circuit protection, current-limiting protection, and over-voltage protection, ensuring that the device is protected from any unwanted overloads.

In addition, the BD9775FV-E2 comes with an active-low watchdog timer, adjustable soft-start, frequency synchronization, and a low-load shutdown. All these features combined make this device a powerful and reliable DC/DC switching controller.

The BD9775FV-E2 can be a perfect choice for various applications, such as mobile phones, notebook and desktop PCs, power-line transmitters, and industrial motor controls. It is a cost-effective and reliable solution for a wide range of power supply designs.

Overall, the BD9775FV-E2 is an excellent DC DC switching controller for many different applications, offering high reliability and versatility. By using its various features, it can ensure a stable output voltage from any DC power source. It can also be used in handheld and/or industrial power applications.
