TPS51513RHBR Frequently Asked Questions (FAQs)

  • A good PCB layout is crucial for the TPS51513RHBR. TI recommends a 4-layer board with a solid ground plane, and the input and output capacitors should be placed close to the IC. The switching node (SW) should be kept away from sensitive nodes, and the feedback network should be routed carefully to minimize noise.
  • The input capacitor (CIN) should be a low-ESR ceramic capacitor with a value between 10uF to 22uF. The output capacitor (COUT) should be a low-ESR ceramic or polymer capacitor with a value between 22uF to 47uF. The capacitor selection depends on the specific application, output voltage, and ripple current requirements.
  • The TPS51513RHBR is rated for operation up to 85°C ambient temperature. However, the device's junction temperature (TJ) should not exceed 125°C. Ensure proper thermal design and heat sinking to maintain a safe operating temperature.
  • The output voltage can be adjusted by changing the resistor divider ratio (RFB1 and RFB2) connected to the FB pin. Use the formula: VOUT = 0.8V x (1 + RFB2/RFB1) to calculate the desired output voltage.
  • The TPS51513RHBR requires a minimum input voltage of 2.7V to ensure proper operation. However, the recommended input voltage range is 3.0V to 5.5V for optimal performance and efficiency.
