The application field and working principle of TPS51124EVM-001 Evaluation Board – DC/DC & AC/DC (Off-Line) SMPS are discussed here. The TPS51124EVM-001 Evaluation Board is an off-line SMPS controller that has both DC/DC and AC/DC capability. It\'s primary applications are high current, low voltage DC-DC power supplies and AC-DC adapters. The board has two voltage regulators, one operating at up to 5A and the other at up to 20A.

The board is powered by four channels of 4.5V to 18V input voltage range. The maximum output current of the DC regulator is 5A, and the maximum output current of the AC regulator is 20A. The board features an I2C interface, allowing the user to configure and monitor the power conversion parameters. It also features a shutdown pin, which allows the user to shut down the power supply in case of an emergency or to prevent an overload.

The TPS51124EVM-001 Evaluation Board utilizes an innovative synchronous rectification technique to eliminate the need for bulky inductors and reduce system cost and total solution size. It offers fixed-speed operation and can be used with ceramic or aluminum electrolytic capacitors to better optimize light load efficiency. The board is also capable of high efficiency operation over a wide input voltage range.

The TPS51124EVM-001 Evaluation Board offers protection against over voltage, over current, and short circuits on the output side. It also provides over temperature protection and under-voltage lockout to prevent damage or false triggering to the system. The onboard load disconnect feature allows for the power supply to automatically shutdown when the line voltage or load current drops below a certain threshold.

The board also includes a wide range of loop compensation components to facilitate wide adjustment range and fast transient response for different loads. The board allows the user to use it as a standalone supply or as part of a multi-output power conversion system.

The TPS51124EVM-001 Evaluation Board provides the user with a complete development platform for testing and developing with the TPS51124 series controller. It also serves as a fast time-to-market solution for custom power supplies and power adapters that require DC/DC or AC/DC power conversion. The board offers the user a reliable, low-cost solution for building high current solutions while providing the necessary flexibility for system design.
