TEXAS INSTRUMENTS TPS84610EVM-003. 评估模块, TPS84610同步降压转换器
The is a fully assembled and tested circuit for evaluating the TPS84610 2.95V to 6V input, 6A output step down Integrated Power Solution. The output voltage can be selected from four preset values using a jumper 3.3V, 2.5V, 1.8V, 1.2V, and 0.8V and has an adjustable switching frequency of 500KHz to 1MHz. The full 6A rated output current can be supplied by the evaluation module. A minimal amount of input and output capacitance is used on the board. Component pads are provided for additional input and output capacitors if desired. Monitoring test points are provided to allow measurement of efficiency, power dissipation, input ripple, output ripple, line and load regulation, and transient response. Control test points are provided for use of the PWRGD, Inhibit/UVLO, synchronization, and slow start/tracking features of the IPS device. The evaluation module uses a recommended PCB layout that maximizes thermal performance and minimizes output ripple and noise.
