TS4997IQT datasheet by STMicroelectronics

TS4997IQT Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  STMicroelectronics provides a recommended PCB layout in the application note AN5096, which includes guidelines for thermal pad connection, copper pouring, and via placement to ensure optimal thermal performance.
• How do I select the correct output capacitor for the TS4997IQT?
  The output capacitor selection depends on the output voltage, output current, and desired ripple voltage. A general guideline is to choose a capacitor with a minimum capacitance of 10uF, low ESR, and a voltage rating above the output voltage. Consult the application note AN5096 for more detailed guidance.
• What is the maximum input voltage that can be applied to the TS4997IQT?
  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 internal components.
• How do I implement overcurrent protection with the TS4997IQT?
  The TS4997IQT has a built-in overcurrent protection feature that can be enabled by connecting a resistor between the OCP pin and the GND pin. The value of the resistor determines the overcurrent threshold. Consult the datasheet and application note AN5096 for more information.
• What is the recommended input capacitor value and type for the TS4997IQT?
  A ceramic capacitor with a value of 1uF to 10uF is recommended for the input capacitor. The capacitor should be placed as close as possible to the VIN pin and have a voltage rating above the maximum input voltage.
