PMIC - Voltage Regulators - Linear: ZSR500GTA

The ZSR500GTA is a high voltage regulator integrated circuit that provides a steady output voltage from an input of an AC voltage. It is an ideal choice for applications requiring an AC voltage inputs, for example, in servers, telecom equipment, medical equipment and other applications with power supply solutions. The ZSR500GTA offers a wide range of features for voltage regulation and protection such as integrated EMI filtering, overvoltage, overload and overcurrent protection, and thermal shutdown. Furthermore, it features two selectable output current ranges – low-range (2A–7A) and high-range (7A-20A).

Application field

The ZSR500GTA operates in a range of applications and has been designed with a broad range of specifications. It is suitable for applications requiring high output current levels in order to provide stability and control to any system. These include but are not limited to:

• Telecommunications systems,
• AV Equipment,
• Medical equipment,
• DC motor drives,
• Power over Ethernet systems,
• Medical Imaging systems,
• High performance computing systems,
• LED lighting systems,
• Robotics and Automation systems.

Working principle

The ZSR500GTA operates on the principle of feedback control. The circuit senses the output voltage and adjusts its current to maintain the steady output voltage. In this way, the ZSR500GTA can be used to regulate the input voltage, providing a consistent output voltage regardless of fluctuating input voltages.

The ZSR500GTA supports two modes of operation: Constant Voltage (CV) mode and Constant Current (CC) mode. Both modes are adjustable and can be set for either low or high output current range. In CV mode, the output voltage is regulated to the set voltage level. The output voltage is monitored using an external voltage divider, and the output current is regulated based on the set voltage level. In CC mode, the output current is regulated to the set current level. The output current is monitored with an external resistor, and the output voltage is regulated based on the set current level.

The ZSR500GTA includes integrated EMI filters to reduce the amount of EMI produced due to its switching operation. It also includes overvoltage, overload and overcurrent protection, as well as thermal shutdown. This ensures the circuit remains safe even during unexpected fault conditions.

In addition, the ZSR500GTA is also flexible in terms of with its operating temperature range, ranging from -40°C to +125°C. This makes it suitable for a wide array of environments and applications.

Conclusion

The ZSR500GTA is a high voltage regulator integrated circuit that provides an adjustable output voltage from an AC voltage source. It features integrated EMI filtering, overvoltage and overload protection, and two selectable output current ranges. This makes the ZSR500GTA a great choice for applications requiring an AC voltage inputs and for applications requiring high output current levels, such as servers, telecom equipment, medical equipment, DC motor drive and power over Ethernet systems. Furthermore, its wide operating temperature range makes it suitable for a variety of environments and applications.
