RT7279GCP Integrated Circuits (ICs)

RT7279GCP is a buck-boost PMIC (Power Management Integrated Circuit) designed specifically for 6V or 7.2V system applications. It is part of a family of Voltage Regulators, DC-DC Switching Regulators. RT7279GCP provides a cost-effective solution for adjusting the output voltage and current levels to optimize the performance of the system.

Application Field

RT7279GCP is an integrated power management IC that is ideal for battery-powered or wired applications. It provides an efficient, low cost method to regulate voltage, adjust current levels and protect against under-voltage and over-voltage conditions. It is also suitable for applications such as charging, emergency shutdown, and output voltage adjustment on TV/ monitor power supplies, AC/DC adapters, tablet computers, and more.

Working Principle

RT7279GCP operates on the switching regulator principle with a control mechanism, which regulates the output voltage by sampling the voltage at the output and comparing it with the reference voltage. When the voltage at the output is less than the reference voltage, the control mechanism increases the duty cycle to increase the output voltage; when the voltage at the output is higher than the reference voltage, the control mechanism decreases the duty cycle to reduce the output voltage. On the primary side, a high frequency PWM switching circuit is used, which can reduce the loss of the magnetic core, minimize the EMI (electromagnetic interference) radiation, and reduce the size of the power inductor. The output voltage range is high (2.6V~7.2V) and the maximum output current is 1.5A.

Safety Measures

RT7279GCP offers excellent over-voltage, under-voltage and over-temperature protection. The over-voltage protection (OVP) feature acts as a safety mechanism to prevent out of range voltage operation. The under-voltage protection (UVP) feature prevents the chances of over-utilization of input energy sources. The over-temperature protection feature stops operation when the temperature reaches a certain level to prevent damage to the device.

Conclusion

RT7279GCP is a buck-boost PMIC designed for 6V or 7.2V system applications. It is part of a family of Voltage Regulators, DC-DC Switching Regulators and is suitable for many application fields. It provides an efficient, low cost method to regulate voltage, adjust current levels and protect against under-voltage and over-voltage conditions.
