DC-DC converters are essential components in today’s world of electrical engineering and technology. Developed to meet increasing demands of power, reliability, and efficiency, they’re used in a variety of applications. One such device is the TPS84621RUQR, a low-voltage, high-efficiency, 125V input/30V-200V output buck converter. This article will explain the application field and working principle of the TPS84621RUQR.
Applications
The TPS84621RUQR is designed to provide a regulated output voltage from a high-voltage (125V) input source. Due to its low voltage capability, it is suitable for applications such as USB-PD (power delivery) systems, OLED lighting, LED lighting, and DC/DC power supplies. It is also suitable for industrial, automotive, consumer, and medical applications. In addition, the device is capable of providing more than 95 percent efficiency, making it an ideal choice for applications that require high efficiency to reduce power losses.
Working Principle
The TPS84621RUQR is a switching mode converter that uses a buck topology to reduce input voltage and provide a regulated output voltage. It uses an internal energy storage switch to regulate the output voltage. The converter consists of an inductor, an energy storage switch, power MOSFET, and PRIMARY CONVERTER CONTROL integrated circuit (IPC). The IPC includes a control loop to ensure constant output voltage. The IPC controls the power MOSFET and the energy storage switch to regulate the output voltage.
The converter operates in two modes: forced continuous conduction mode (FCCM) and discontinuous conduction mode (DCM). During FCCM, the current in the inductor flows in continuous direction, while it is switched off in the DCM. The converter switching happens at a very high frequency to ensure a low ripple voltage. The circuit also features built-in protections such as short circuit protection, over temperature protection, and open loop protection. This ensures safe operation and a reliable performance even at high input voltages.
Conclusion
The TPS84621RUQR is an ideal choice for a variety of applications, such as USB-PD systems, OLED lighting, LED lighting, and DC/DC power supplies, due to its low voltage capability combined with high efficiency. It uses a buck topology and integrated IPC to keep the output voltage regulated. It also includes built-in protections for reliable performance even at high input voltages. All in all, it is an excellent choice for applications requiring high efficiency and reliability.
