LTC1703CG#PBF Frequently Asked Questions (FAQ)
-
The recommended PCB layout for the LTC1703CG involves placing the input capacitors close to the VIN and GND pins, and using a solid ground plane to reduce noise and improve thermal performance. A 4-layer board with a dedicated power plane and a solid ground plane is recommended.
-
The input capacitors should be selected based on the input voltage range, ripple current, and ESR requirements. A low-ESR capacitor with a high ripple current rating is recommended. The capacitor value should be at least 10uF, and X5R or X7R dielectrics are recommended for their low ESR and high reliability.
-
The maximum output current of the LTC1703CG is 3A, but it can be limited by the thermal performance of the package and the PCB. The output current should be derated based on the ambient temperature and the thermal resistance of the package and PCB.
-
The output voltage of the LTC1703CG can be adjusted by using a resistive divider network between the output and the FB pin. The resistors should be chosen to provide a stable output voltage and to minimize the noise and ripple.
-
The PG pin on the LTC1703CG is a power good output that indicates when the output voltage is within regulation. It can be used to enable or disable other circuits in the system, or to provide a status indication to a microcontroller or other logic circuit.
