TSM104WIDR datasheet by Texas Instruments

TSM104WIDR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Texas Instruments provides a recommended PCB layout in the TSM104WIDR datasheet (section 10.2) and in the 'TSM104WIDR Thermal Layout Guidelines' application note (SLVAE66). It's essential to follow these guidelines to ensure optimal thermal performance and prevent overheating.
• How do I select the correct input capacitor values for my application?
  The input capacitor values depend on the input voltage, output voltage, and output current. Texas Instruments provides a capacitor selection guide in the TSM104WIDR datasheet (section 7.3.1) and in the 'TSM104WIDR Input Capacitor Selection' application note (SLVAE65). You can also use the TI Power Designer software to help with capacitor selection.
• What is the maximum output current I can draw from the TSM104WIDR?
  The maximum output current of the TSM104WIDR is 4A. However, the actual output current capability depends on the input voltage, output voltage, and ambient temperature. Be sure to check the datasheet (section 6.3) for the output current derating curves to ensure you're operating within the recommended specifications.
• How do I implement overcurrent protection (OCP) with the TSM104WIDR?
  The TSM104WIDR has a built-in overcurrent protection feature. To implement OCP, you need to connect a sense resistor (Rs) between the output pin and the GND pin. The OCP threshold is set by the value of Rs. Texas Instruments provides more information on OCP implementation in the datasheet (section 7.3.4) and in the 'TSM104WIDR Overcurrent Protection' application note (SLVAE64).
• What is the recommended input voltage range for the TSM104WIDR?
  The recommended input voltage range for the TSM104WIDR is 2.7V to 5.5V. Operating the device outside of this range may affect its performance, efficiency, or reliability. Be sure to check the datasheet (section 6.1) for the recommended operating conditions.
