STMPS2161MTR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A 2-layer or 4-layer PCB with a solid ground plane and thermal vias under the device can help to dissipate heat efficiently. It's also recommended to use a thermal pad on the bottom of the device.
• How do I ensure reliable operation at high temperatures?
  Ensure that the device is operated within the recommended temperature range (TJ = -40°C to 150°C). Use a heat sink or thermal interface material to improve heat dissipation. Also, consider derating the device's power dissipation at high temperatures.
• What is the recommended input capacitor value and type for the STMPS2161MTR?
  A 10uF to 22uF X7R or X5R ceramic capacitor is recommended for the input capacitor. The capacitor should be placed as close to the device as possible to minimize parasitic inductance.
• How do I minimize electromagnetic interference (EMI) in my design?
  Use a shielded inductor, keep the switching node (SW) as short as possible, and use a common-mode choke to reduce EMI. Also, ensure that the PCB layout is optimized for minimal radiation and that the device is placed away from sensitive circuits.
• What is the recommended output capacitor value and type for the STMPS2161MTR?
  A 10uF to 47uF X7R or X5R ceramic capacitor is recommended for the output capacitor. The capacitor should be placed as close to the device as possible to minimize parasitic inductance.
