Additionally, the converter has been designed with protection against present and future automotive voltage and current transients.

Working Principle

The XCL221B121ER-G is a DC/DC converter that works in two stages. In the first stage, a full-wave bridge rectifier is used to convert the input AC voltage into DC. This DC voltage is then regulated to the desired output voltage using an onboard boost regulator. The result is a reliable and efficient source of DC power.

The onboard boost regulator uses pulse-width modulation (PWM) to regulate the output voltage. In this type of regulation, the output voltage is adjusted by varying the duty cycle of the switching MOSFETs. When the duty cycle is high, the output voltage is high, and when the duty cycle is low, the output voltage is low. This type of regulation is very fast and efficient, allowing the XCL221B121ER-G to regulate the output voltage with minimal power dissipation.

The XCL221B121ER-G also features built-in protections for overvoltage, short-circuit, and overcurrent. These protections ensure that the converter will not be damaged in the event of a fault in the input or output circuits. The protections also protect the converter itself from excessive current or voltage, as well as from dangerous conditions such as a short-circuit.

Conclusion

The XCL221B121ER-G is a highly efficient, robust, and powerful DC/DC converter that is suitable for a wide range of applications. It is capable of providing a wide range of output voltages and currents with built-in protections against overvoltage, short-circuit, and overcurrent conditions. The onboard boost regulator uses pulse-width modulation to regulate the output voltage, making it fast and efficient. The XCL221B121ER-G is suitable for use in distributed power systems, including telecom base stations, server systems, and data centers, as well as advanced automotive systems.
