Other Parts Discussed in Thread: TLV62565, LM26420
Tool/software:
Using TLV62565 to power TMS320F28377, with a 5V input, one to 1.2V and the other to 3.3V, DSP steady-state current of 90mA. When powered on, the measured 3.3V TLV62565 output shows the following waveform. I would like to know why there is a platform voltage during the establishment process of TLV62565 output voltage? 2. When using LM26420 to supply 3.3V, there is no such phenomenon; 2. Is there any way to remove the voltage from this platform? We are concerned that there may be power supply failures when the DSP program is running at full load. May I ask if the DSP can operate normally when the platform voltage is present?
