Hi, Team
A car infotainment customer Flyaudio is using TPS65265 in their project. The DCDC2 is output 3.3V for eMMC.
When system power up, the output current will change between 0 and 300mA rapidly. And it makes big spur on output voltage. The Dynamic Response of Load Transient is slow. Could you advice how to optimize it?
Here is customer schematic:
Here is waveform:
CH1: Output voltage (AC coupled)
CH2: Wavefrom on LX2 (pin 11)
CH4: Output current
Thanks
Kevin
