The TPS65053EVM-217 is an evaluation module for Texas Instruments\' TPS65053 3-MHz DC/DC & AC/DC (off-line) synchronous resonant converter.The TPS65053EVM-217 is designed to demonstrate the high-efficiency and high-performance capabilities of the TPS65053.The evaluation module features an adjustable output voltage and running frequency with an onboard USB-UART interface, making it perfect for testing and measuring low-power designs in consumer product applications.

The TPS65053EVM-217 targets applications such as smartphone chargers, USB wall adapters, security systems, and digital audio amplifiers. It provides a table in the data sheet to circuit for selecting an appropriate transformer or inductor from the required core range for a specific application. The maximum output power is 17 watts, and the output voltage range is 0.5V to 14V. The maximum operating frequency is 3MHz.

The internal TPS65053 power supply includes a high-frequency controller, high-efficiency PWM converter, MOSFET gate drive IC, power FETs, an onboard transformer, and current sensing. The TPS65053 includes multiple protection features, such as over temperature protection, short circuit protection, and open-circuit protection.

The TPS65053EVM-217 operates on an input voltage of 4.5V to 14V and utilizes a Synchronous Buck-Boost Resonant (SBR) topology. The SBR topology works in 4 phases, startup/sleep, boost, continuous conduction mode (CCM), and discontinuous conduction mode (DCM). The SBR controller adjusts the inductor current amplitude to achieve the highest efficiency and makes dynamic efficiency and transient response better than PWM or PFM.

The TPS65053EVM-217 also includes the TI MSP-FET430UIF USB emulation interface, which charges a USB power delivery (PD) 2.0-compliant device from USB Type-C or micro-USB ports. The USB emulation interface includes the appropriate resistors and capacitors, making it easy to set up for testing and measuring USB PD 2.0 designs. Additionally, the TPS65053EVM-217 includes an onboard USB-UART interface, which is connected to the MCU downstream port and can be used for troubleshooting.

The TPS65053EVM-217 evaluation module provides an easy way to evaluate the performance of the TPS65053 DC/DC & AC/DC (off-line) synchronous resonant converter. It features an adjustable output voltage and frequency, USB emulation interface, and an onboard USB-UART interface. The TPS65053EVM-217 is ideal for testing and measuring low-power designs in consumer product applications, such as smartphone chargers, USB wall adapters, security systems, and digital audio amplifiers.
