Hello Adam,
If you need additional cooling you would have to use external heat sinks connecting to the gnd of the device. On the PCB side you can have additional GND layers , larger PCB area and more gnd vias to dissipate out the heat. From power consumption…
Hello Will,
Thank you for supporting the UCC27710 gate driver. To determine the gate driver power dissipation, the gate charge, VDD level and switching frequency are needed to calculate the power dissipation. The UCC27710 datasheet section 9.2.2 has…
Part Number: IWR6843ISK Other Parts Discussed in Thread: IWR6843 Tool/software: Hello,
I am currently trying to follow the steps outlined in xWR6843 Low Power Modes User Guide to implement a low power mode for the oob Demo iwr6843ISK. According to the…
Part Number: TPS7A91 Hello,
I’m currently analyzing the power consumption of the TPS7A91 LDO regulator, and I’d like to clarify how to correctly determine its quiescent or operating current .
Could you please explain which parameter in the datasheet…
Hi Sumayyah,
unfortunately there are severuel potential issues within your layout:
- first you are using thermals to connect the components within the power stage. This makes soldering easier but adds a lot of inductance and this is very bad within…
Dear Bob,
thanks for your tips and sorry for late reply, It took some time to measure the supply source ripples and design the layout.
the power source is an external switching supply and the ripple without any load could be seen below. Maybe it is…
Part Number: CC1310 Tool/software: Hi,
I would like to implement Low Battery detection in my remote based on CC1310 powered by 2xAAA.
Could you give me some tip how to start it? I am talking about measure power supply connected to some analog input…
