Hi Chunjie,
Thank you for checking the FET soldering. CSD87331Q3D is a great choice for making manufacturing easier.
For output ripple on BUCK5 - it looks like per schematic there is only 1x10uF capacitor? We recommend minimum of 22 uF. Increasing…
Hi Shyam Daram,
BUCK1/2/6 will have no issue going to 7A ouptut on the buck controllers (BUCK1/2/6) if the right FETs and inductor are chosen and the input power is able to support it. On page 110 of the TPS650864x datasheet there is a list of FETs…
Part Number: TPS51285A Other Parts Discussed in Thread: CSD87331Q3D , Hi
We have an project design TPS51285A and I am debugging of damaging high-low side MOSFET (CSD87331Q3D, U70 of attached schematic). Below is the SW waveform, the voltage is not over…
na na78 said: 1. In this power map, TPS544C25 is used to supply 0.72V which is different voltage level with VCCBRAM. The purpose of TPS544C25 implemented is just to supplying different voltage with BUCK2, isn't it? Yes and no. TPS544C25 can be used to…
Other Parts Discussed in Thread: TPS51116 , CSD87331Q3D Customer's TPS51116 circuit make large noise, customer will connect 30Ω resister between VBST to C2104.

Hi Vincent,
Thanks for promoting TI FETs at your customer. Below is a list of all parts in the Q3D (3.3 x 3.3mm SON) package and the HBM pass voltage. The CSD87333Q3D and CSD87334Q3D include ESD protection diodes and have a much higher HBM pass voltage…
Hi Partha,
You can find the TI reference design for Apollo Lake processor in the Intel Document Library under IBL#560683. It utilizes the CSD87381P for BUCK1/6 and CSD87588N for BUCK2 but there are other options, for example the CSD87331Q3D for BUCK1…
Hi,
TI recommended FET's are CSD87331Q3D, CSD87381P, and CSD87588N. However other FETs you mentioned should also work, but we cannot tell whether they work seamlessly with this controller. In general Rds-on, Gate charge/dynamic switching parameters…
Part Number: TPS51225 Dear Teams,
My customer is using TPS51225, and the schematic diagram attached here. Normally, it has 12V input and 5V & 3.3V dual output. The 3.3V will used as a power supply for the CPU. Previously, they are running everything…
