Part Number: TPS65400 I have the following inquiry regarding the external clock of the TPS65400.
TI provides an AC coupling structure as shown in Figure 8-10 when operating the TPS65400 with an external clock.
The datasheet specifies that the absolute…
Part Number: TPS65400
Hello,
We are currentlty using the TPS65400 in our design to take 12V and generate the following rails:
SW1 - 6V
SW2 - 3.3V
SW3 - 1.8V
SW4 - 1.2V
At this time, small batch of units are failing after being in a case…

Part Number: TPS65400-Q1 1.Problem Background Description
On November 8, 2025, the Quality Department reported that a customer returned a KP1201 instrument with a black screen fault. After disassembly, no burn marks or corrosion were found in the…
Part Number: TPS65400 Tool/software: Hi Team,
Customer hope that during system startup or charging, no power is supplied to chips other than the MCU. When needed, the MCU should control the PMIC to supply power.
Currently, on the customer's schematic…
