RT8023GQW application field and working principle

Introduction

The RT8023GQW is one of Richtek’s low-side single channel voltage regulator IC (Integrated Circuit) which falls in the category of PMIC (Power Management IC) Voltage Regulators, being part of the Linear + Switching category. It is specially developed to meet the demands of personal computer and server system infrastructure, and provides comprehensive over-voltage protection (OVP) for system components configuration in its very wide application field. RT8023GQW consists of an integrated low-side MOSFET for Circuit-protection, a thermal sensor for the low-side MOSFET, current source load source and a Linear + Switching controller. It is designed in an SOP-8L package.

Application Field

The RT8023GQW is perfect for a large amount of applications ranging from personal computers to server systems. Its features make it a very efficient voltage regulator for a selection of power systems, especially those with the possibility of synchronization with the master clock of the system. Additionally, the combination of switching and linear voltage regulator makes it ideal first devices in the line of heavy system components with voltage requirements ranging from 0.9 V to 24 V. Therefore, its ideal field of application includes, but is not limited to, DRAM modules, SRAM/MRAM modules, as well as LCD monitors and television sets.

Design and Working Principle

RT8023GQW has a typical constant voltage of 1.8V and a current rating of 10V which means it can support a load capacity of up to 100W. It features a single low-side MOSFET connected technology which ensures low UPSR losses, fast output voltage settling, and a ‘zero risk’ of over-voltage tolerance. Additionally, the RT8023GQW integrates two major functional blocks for ensuring a reliable current source load source and OVP protection, along with a linear-switching controller designed to ensure a high-efficiency supply.The RT8023GQW linear + switching design combines two principle types of energy conversion. The first is the DC-DC buck converter which takes input voltage of 24V and provides DC to DC output power that is regulated over a wide operating range of 0.9V to 24V. This is typically used in applications requiring a wide voltage range and high noise immunity. The second is the voltage stabilizing Linear regulator. The Linear regulator typically supports a lower duty cycle than the DC-DC converter and its output voltage is more accurately controlled and more stable with high line and load conditions.Lastly, RT8023GQW they includes an embedded Overtemperature Protection (OTP) circuit which prevents damage to the system due to excess temperature output by safety switching off the output when the junction temperature of the device reaches 170°C.

Conclusion

In conclusion, RT8023GQW provides a reliable low-side single channel voltage regulator, ideal for use in wide range of applications from personal computers to server systems. It combines a high-efficiency low-side MOSFET for circuit protection with a linear + Switching controller and a current source load source to ensure an accurate voltage regulation in as short a time as possible and a high-tolerancing OVP circuit for protection. It features a wide range of operating voltages from 0.9V to 24V, with the capability of synchronizing with the master clock of the system, as well as including an embedded Overtemperature Protection (OTP) circuit.
