TSM104WAID datasheet by Texas Instruments

TSM104WAID Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Texas Instruments provides a recommended PCB layout in the TSM104WAID datasheet, which includes a thermal pad connected to a large copper area on the PCB to dissipate heat. Additionally, it's recommended to use a 4-layer PCB with a solid ground plane to reduce thermal resistance.
• How do I ensure accurate voltage regulation with the TSM104WAID?
  To ensure accurate voltage regulation, it's essential to follow the recommended input and output capacitor values and types, as specified in the datasheet. Additionally, the input voltage should be within the recommended range, and the output voltage should be set using a precise voltage divider network.
• What is the maximum input voltage that the TSM104WAID can handle?
  Although the datasheet specifies a maximum input voltage of 18V, it's recommended to limit the input voltage to 15V to ensure reliable operation and prevent damage to the device.
• How do I protect the TSM104WAID from overcurrent and short-circuit conditions?
  The TSM104WAID has built-in overcurrent protection (OCP) and short-circuit protection (SCP). However, it's still recommended to add external protection components, such as fuses or PTC resistors, to prevent damage from excessive current or voltage surges.
• What is the typical dropout voltage of the TSM104WAID?
  The typical dropout voltage of the TSM104WAID is around 1.5V, which means that the input voltage should be at least 1.5V higher than the output voltage to ensure proper regulation.
