TPS51217DSCT Frequently Asked Questions (FAQ)

  • Texas Instruments provides a recommended PCB layout in the datasheet (Figure 23) and in the application note SLVA883. It's essential to follow these guidelines to minimize noise, ensure proper thermal performance, and optimize the overall performance of the TPS51217DSCT.

  • The selection of input and output capacitors depends on the specific application requirements. TI recommends using low-ESR capacitors with a minimum capacitance of 10uF for the input and 22uF for the output. The capacitor selection guide in the datasheet (Table 6) can help with this process.

  • The TPS51217DSCT is rated for operation up to 85°C ambient temperature. However, it's essential to consider the thermal design and ensure proper heat dissipation to maintain a junction temperature below 125°C for reliable operation.

  • The soft-start feature can be configured using the SS pin. A capacitor connected between the SS pin and GND sets the soft-start time. The datasheet provides a formula to calculate the soft-start time based on the capacitor value (Equation 12).

  • The EN (Enable) pin is used to enable or disable the device. When the EN pin is pulled high, the device is enabled, and when it's pulled low, the device is disabled. This pin can be used to implement power sequencing or to shut down the device during low-power modes.
