TLS1233N datasheet by Texas Instruments

TLS1233N Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the TLS1233N?
  Texas Instruments recommends a compact layout with the TLS1233N placed close to the power source, and the input and output capacitors placed as close as possible to the device. A 4-layer PCB with a solid ground plane is also recommended to minimize noise and EMI.
• How do I ensure the TLS1233N is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and placement guidelines, and use a sufficient output capacitor (at least 10uF) with a low ESR. Additionally, the input capacitor should be at least 1uF with a low ESR. Also, ensure that the output voltage is within the recommended range and the device is operated within the specified temperature range.
• What is the maximum input voltage that the TLS1233N can handle?
  The TLS1233N can handle a maximum input voltage of 18V, but it's recommended to operate it within the specified range of 7V to 15V for optimal performance and reliability.
• Can I use the TLS1233N in a high-temperature environment?
  The TLS1233N is rated for operation up to 125°C, but it's recommended to derate the output current and voltage as the temperature increases to ensure reliability and prevent overheating. Consult the datasheet for specific derating guidelines.
• How do I calculate the output voltage ripple of the TLS1233N?
  The output voltage ripple of the TLS1233N can be calculated using the formula: ΔVout = (Iout * RESR) / (fSW * COUT), where Iout is the output current, RESR is the equivalent series resistance of the output capacitor, fSW is the switching frequency, and COUT is the output capacitance. Consult the datasheet for specific values and guidelines.
