LT3046ATC+ Frequently Asked Questions (FAQs)

  • A good PCB layout for the LT3046ATC+ involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the input and output traces. Additionally, it's recommended to use a Kelvin connection for the output voltage sense pins to reduce noise and improve accuracy.
  • To ensure stability, make sure to follow the recommended compensation network configuration, use a minimum output capacitance of 10uF, and keep the output voltage sense pins close to the output capacitors. Additionally, avoid using long output traces and minimize the inductance of the output capacitors.
  • The LT3046ATC+ can handle input voltages up to 36V, but it's recommended to operate within the specified input voltage range of 2.9V to 32V for optimal performance and reliability.
  • The LT3046ATC+ is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliability and prevent thermal shutdown.
  • The output voltage of the LT3046ATC+ can be programmed using an external resistor divider network connected to the VOUT pin. The output voltage is determined by the ratio of the resistors and the internal reference voltage.
