LTM4601 - IC 17 A SWITCHING CONTROLLER, 850 kHz SWITCHING FREQ-MAX, PBGA133, 15 X 15 MM, 3.42 MM HEIGHT, ROHS COMPLIANT, MS-028, BGA-133, Switching Regulator or Controller
The maximum operating temperature range for the LTM4601AIY#PBF is -40°C to 125°C.
To ensure proper thermal management, make sure to provide adequate heat sinking, use a thermally conductive PCB material, and keep the device away from heat sources. Also, consider using a thermal interface material (TIM) between the device and the heat sink.
The recommended input capacitor value is 10uF to 22uF, and the type should be a low-ESR ceramic capacitor, such as X5R or X7R, to minimize input ripple and ensure stable operation.
To optimize the output filter design, use a combination of capacitors and inductors to filter out high-frequency noise and ripple. A good starting point is to use a 10uF output capacitor and a 1uH output inductor, and then adjust the values based on the specific application requirements.
The maximum output current capability of the LTM4601AIY#PBF is 1A per phase, and up to 2A total output current when both phases are used in parallel.
