Part Number: TPS53355 Hi,
1) How many seconds above the current limit set by the 21pin does overcurrent protection start to work?
2) What is the unit for each parameter in equation (2) on datasheet P18?
Best Regards,
Nishie
Hello Jimmy,
The part number in the thread is TPS53355 but the SCH has a different part number, can you please confirm the right part number
Yuchang Zhang can review the TPS566335
Thanks

Hey Xinjie,
The VREG may jitter due to fluctuations on the input voltage to the LDO. When a load step happens, the voltage at the input can drop momentarily, causing a drop on the VREG input voltage, this is why decoupling capacitor placement and values…
