The RP90Q-4812SRW/N-HC is a high current, dual output, non-isolated buck regulator specially designed to provide a steady power supply for board mounted applications. It is a type of DC-DC converter, capable of providing up to 12A of output current over a wide output voltage range of 0.85 to 48V. It’s compact size, high efficiency, and robust design make it an ideal choice for applications where space is limited and power demands are high.

The RP90Q-4812SRW/N-HC utilises synchronous rectification, allowing for high efficiency and small heat dissipation. The regulator also features a wide input voltage operation range of 4.5 to 90V, allowing for compliance with a range of input voltage requirements. It features a high-accuracy reference voltage, and is adjustable with an external resistor, enabling it to be used in many applications with varied power requirements.

The RP90Q-4812SRW/N-HC can be used in a wide range of applications, including computers, consumer electronics, industrial control systems, and telecommunications. It is capable of providing a steady and reliable power supply in these types of applications. Additionally, it can be used in automotive and aviation applications, as it has a wide temperature operation range from -40 to 85°C.

The grounding of the board mounted RP90Q-4812SRW/N-HC is also an important factor to consider. If the ground path resistance is too high, it can cause ground loops that can cause noise or instability in the output voltage. Additionally, the regulator should have a spaced 3.3mm between the top and bottom of the board for optimal cooling performance.

In terms of its working principle, the RP90Q-4812SRW/N-HC utilises synchronous rectification, which is a process whereby current flows in both directions through the power switches (MOSFETs). The working of the buck regulator involves the steps of energy conversion, step control, energy storage, energy delivery, and voltage regulation. In the energy conversion stage, the power source is converted into an AC waveform, then filtered to provide a clean DC input current. The step control stage determines the exact input to output voltage ratio by controlling the duty cycle of the switching circuit. In the energy storage stage, an inductor is used to store energy. In the energy delivery stage, this stored energy is output to the load so that the output voltage is regulated.

The voltage regulation stage involves a voltage reference, which is compared to the output of the feedback loop to determine if the output voltage is within the acceptable range. If the output voltage is too low, the PWM signal is adjusted to increase the voltage, and if the output voltage is too high, the PWM signal is adjusted to reduce the voltage. This process repeats until the desired output voltage is reached.

In summary, the RP90Q-4812SRW/N-HC is a type of DC-DC converter that features high current, dual output, non-isolated buck regulator. It is capable of providing up to 12A of output current over a wide output voltage range and features a wide input voltage operation range. Its synchronous rectification design allows for high efficiency and robust design, making it suitable for a wide range of applications. Additionally, its working principle involves energy conversion, step control, energy storage, energy delivery, and voltage regulation stages.
