Introduction to RTQ2130B-50GQW-QT

The RTQ2130B-50GQW-QT is a DC/DC switching regulator developed by Richtek Technology. It is designed to provide both efficient and reliable voltage conversion solutions for power management applications. It offers excellent load current and output ripple performance to meet the needs of an array of devices.

Application Field:

The RTQ2130B-50GQW-QT is suitable for a variety of power management applications. It is optimized for the battery-powered and high-backlight LCD displays found on portable electronic devices such as mobile phones, tablet PCs, and portable game consoles. It can also provide power for various linear regulators, step-down controllers, and buck converters.

Working Principle:

The RTQ2130B-50GQW-QT operates with a basic two-stage voltage conversion method. First, a high-efficiency PWM step-down converter produces a substantially lower output voltage from an input voltage range of 4.75 V to 60 V. This enables it to efficiently provide power to low- and mid-voltage connected components. Then, a low-input current LDO regulator takes the output of the step-down converter and produces the needed output voltage.

The RTQ2130B-50GQW-QT features an excellent efficiency at light and heavy load conditions, with reduced power losses and heat dissipation. It features a high power density design and can deliver up to 6 amperes in a very small thermal-limited package. In addition, it provides a wide full-load temperature range of -20°C to +125°C.

The RTQ2130B-50GQW-QT is equipped with a low ESR output capacitor that is connected between the LDO output and ground. This allows for a stable output voltage with minimal ripple and noise, resulting in better system performance, increased operation life, and better reliability.

The RTQ2130B-50GQW-QT also features a built-in over-voltage protection and current limit protection that protect against current overloads. The on-chip power good signal provides system monitoring and feedback for the user. The programmable switching frequency allows the user to optimize the design with respect to size, performance, and cost.

Conclusion:

The RTQ2130B-50GQW-QT is a DC/DC switching regulator that provides reliable and efficient voltage conversion solutions for an array of power management applications. It features a high-efficiency step-down converter and an ultra-low-noise LDO output regulator. The RTQ2130B-50GQW-QT is suitable for battery-powered and high-backlight LCD displays, as well as various linear regulators, step-down controllers, and buck converters. It also features integrated protection and monitoring, as well as a programmable frequency that allows the user to optimize size, performance, and cost.
