TPS54060EVM-590

TPS54060 DC to DC Converter and Switching Regulator Chip 30VDC Output Evaluation Board

The is an evaluation module for TPS54060 DC/DC converter, designed to provide up to a 0.5A output from an input voltage source of 3.5V to 60V. This evaluation module is designed to demonstrate transformer coupled split rail operation with dual outputs providing ±18V at up to ±100mA. The -18V output is used as the ground reference for the TPS54060 in this application, which allows the sum of the positive and negative outputs to be divided and sent to the VSNS pin for regulation. The switching frequency is externally set to 300KHz with a resistor at the RT/CLK pin, and the compensation components are also external to the integrated circuit. The high-side MOSFET is incorporated inside the TPS54060 package along with the gate drive circuitry. The low drain to source on resistance of the MOSFET allows the TPS54060 to achieve high efficiency and helps keep the junction temperature low at high output currents.
