LT1963AET Frequently Asked Questions (FAQs)

  • The recommended input capacitor value for the LT1963AET is 10uF to 22uF, depending on the input voltage and output current requirements. A larger capacitor value can help to reduce input ripple and improve transient response.
  • To minimize noise and ensure good performance with the LT1963AET, it is recommended to follow good PCB layout practices such as separating the input and output sections, using a solid ground plane, and keeping sensitive nodes away from noisy areas. Additionally, the datasheet provides a recommended PCB layout and thermal pad connection guidelines.
  • The maximum ambient temperature that the LT1963AET can operate in is 85°C. However, the device can operate at higher temperatures with derating. It is recommended to consult the datasheet for thermal derating curves and to ensure that the device is properly heat-sinked.
  • Yes, the LT1963AET is qualified for use in high-reliability and automotive applications. It meets the requirements of AEC-Q100 and is manufactured in accordance with Analog Devices' quality and reliability standards.
  • The output voltage ripple of the LT1963AET can be calculated using the equation: ΔVout = (Iout * ESL) / (Cout * fsw), where ΔVout is the output voltage ripple, Iout is the output current, ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency. The datasheet provides more information on output voltage ripple and how to minimize it.
