LTC4009 - IC BATTERY CHARGE CONTROLLER, 633 kHz SWITCHING FREQ-MAX, PQCC20, 4 X 4 MM, 0.75 MM HEIGHT, LEAD FREE, PLASTIC, MO-220WGGD-1, QFN-20, Switching Regulator or Controller
The maximum operating temperature range for the LTC4009CUF-1#TRPBF is -40°C to 125°C.
To ensure reliable operation in high-temperature environments, it is recommended to follow proper thermal design and layout guidelines, such as providing adequate heat sinking and airflow, and using thermal interface materials to reduce thermal resistance.
The recommended input capacitor value is 10uF to 22uF, and the recommended type is a low-ESR ceramic capacitor, such as an X5R or X7R dielectric.
To optimize the layout for minimum EMI and noise, it is recommended to follow proper PCB design guidelines, such as keeping the input and output traces separate, using a solid ground plane, and minimizing loop areas and trace lengths.
The maximum output current capability of the LTC4009CUF-1#TRPBF is 9A, but it is recommended to derate the output current based on the ambient temperature and the thermal design of the system.
