TPS51727RHAR Frequently Asked Questions (FAQs)

  • 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 TPS51727RHAR.
  • The output capacitor selection depends on the output voltage, output current, and desired ripple voltage. TI recommends using a low-ESR capacitor with a minimum capacitance of 10uF. A higher capacitance can be used for improved ripple rejection and transient response. Refer to the datasheet (Section 8.2.2.2) for more information.
  • The TPS51727RHAR has an absolute maximum input voltage rating of 6.5V. However, the recommended operating input voltage range is 3.5V to 5.5V. Exceeding the absolute maximum rating can damage the device.
  • The soft-start feature is enabled by connecting the SS pin to a capacitor to GND. The soft-start time is determined by the capacitor value and the internal resistor (R_SS). Refer to the datasheet (Section 8.3.3) for more information and calculation examples.
  • The EN (Enable) pin is used to enable or disable the device. When EN is high, the device is enabled, and when EN is low, the device is disabled. The EN pin can be connected to a logic signal or a power-good signal to control the device's operation.
