LTM4644IY#PBF Frequently Asked Questions (FAQ)
-
A 4-layer PCB with a solid ground plane and thermal vias is recommended. The device should be placed near a thermal pad or heat sink to dissipate heat efficiently.
-
Ensure that the input voltage rises monotonically during start-up and falls monotonically during shutdown. A soft-start circuit can be used to control the input voltage ramp rate.
-
The maximum capacitive load is 10nF. Exceeding this value may cause instability or oscillations.
-
Use a shielded enclosure, keep sensitive components away from the device, and use a common-mode choke or ferrite bead to filter the output.
-
A pi-filter (L-C-L) or a T-filter (L-C-R-L) configuration is recommended to reduce input ripple and noise.
