LTC2938IDE#PBF Frequently Asked Questions (FAQ)

  • The recommended layout and placement for the LTC2938IDE#PBF involves keeping the device away from high-current carrying traces, using a solid ground plane, and placing the input and output capacitors close to the device. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended. Additionally, the device should be placed near the power source to minimize voltage drops.

  • To ensure the LTC2938IDE#PBF is stable and does not oscillate, it is recommended to follow the layout and placement guidelines, use a sufficient output capacitor with a low ESR, and add a small ceramic capacitor (e.g., 10nF) between the VOUT and GND pins. Additionally, the input voltage should be well-regulated and the device should be operated within its recommended operating conditions.

  • The maximum output current that the LTC2938IDE#PBF can deliver is 3A. However, the output current should be derated based on the ambient temperature and the input voltage. The device should be operated within its recommended operating conditions to ensure reliable operation.

  • The output voltage of the LTC2938IDE#PBF can be programmed using an external resistor divider network connected to the VFB pin. The output voltage can be calculated using the formula: VOUT = 0.8V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.

  • The power dissipation of the LTC2938IDE#PBF depends on the input voltage, output voltage, and output current. The device has a thermal shutdown feature that turns off the device when the junction temperature exceeds 150°C. The power dissipation can be estimated using the formula: PDISS = (VIN - VOUT) x IOUT + VIN x IQ, where IQ is the quiescent current.
