DCH010515DN7 datasheet by Texas Instruments

DCH010515DN7 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Texas Instruments recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to ensure optimal thermal performance.
• How do I ensure reliable operation at high temperatures?
  To ensure reliable operation at high temperatures, it is recommended to derate the device's power dissipation according to the thermal derating curve provided in the datasheet, and to ensure good thermal conduction to the PCB and heat sink.
• What is the recommended input capacitor value and type for this device?
  The recommended input capacitor value is 10uF to 22uF, and a low-ESR ceramic capacitor such as X5R or X7R is recommended to ensure stable operation.
• How do I prevent electromagnetic interference (EMI) in my design?
  To prevent EMI, it is recommended to use a shielded inductor, keep the switching node (SW) away from sensitive nodes, and use a common-mode choke or ferrite bead on the input lines.
• What is the maximum allowed voltage on the VIN pin?
  The maximum allowed voltage on the VIN pin is 18V, and exceeding this voltage may damage the device.
