RT9114BGQV Application Field and Working Principle

RT9114BGQV are positive adjustable step-down DC-DC controllers designed for extreme power density applications and belong to the PMIC - Voltage Regulators - DC DC Switching Regulators category. The RT9114BGQV are capable of converting a 4.5V to 28V input voltage to a 0.7V to 18V output voltage. The wide input and output ranges enable a variety of applications such as point of load voltage regulation, power adapters, and notebooks and other portable electronic devices.

The RT9114BGQV are equipped with the advanced features of the Step-Down DC-DC family including: Burst Mode, Fixed Frequency, Power Good, and programmable Over Current Protection. These features enable the DC-DC controller to offer a high efficiency conversion and fast transient response when driving heavy load transients across a wide input voltage range. It is also possible to reduce the output noise due to its low ripple frequency on the output voltage.

The RT9114BGQV application fields cover not only notebook computers, AC/DC adapters, LED drivers, LED backlights, industrial applications, automotive applications and motor control applications, but also extend to the high-end field of photovoltaic inverters and data centers. In addition, the RT9114BGQV can also be used in environments with harsh environmental conditions such as high temperature.

The working principle of the RT9114BGQV is based upon the same monolithic integrated circuit (IC) found in other DC-DC switching regulators of the same family. Essentially, power is converted from the higher input voltage to the lower output voltage. It does this by using a voltage mode switching circuit with a single feedback loop. This switching circuit is used to pulse-width modulate the output voltage.

First, the voltage at the OUT pin is compared to a fixed reference voltage. This reference voltage is determined by a settable DAC which is used to program the output voltage. If the output voltage is higher than the reference voltage, the controller will reduce the current flow. If the output voltage is lower than the referencevoltage, the controller will increase the current flow.

The RT9114BGQV is also equipped with a feedback loop to monitor the output voltage and adjust the current flow. This is done using a ramp-up/down controller which senses the current level in the output stages. As the output voltage is adjusted, the ramp-up/down controller will adjust the current flow accordingly.

Finally, the RT9114BGQV has a variety of protection features built in to protect the user from harmful currents or voltages. This includes under voltage lockout, current limit, and over temperature protection. These protection measures ensure that the RT9114BGQV can provide a reliable and safe power conversion.

The RT9114BGQV is an advanced and versatile DC-DC step-down controller that is capable of providing high efficiency, fast transient response, and low output ripple noise across an ultra-wide input and output voltage range. With its advanced features and protection mechanisms, the RT9114BGQV is an ideal choice for high power density applications and environments with harsh environmental conditions.
