Part Number: TPS65251 Hi
Could you tell me the EN delay of TPS65251RHAR.
After Hi level voltage is applied externally to EN (1/2/3), how long does it take for the output voltage to start to rise.
Please tell me Min / TYP / Max.
Also, if there is a time…

Our customer doing TPS65251 device.
If see datasheet, Recommend 4-Layer PCB.
But Our customer want using TPS65251 in 2-Layer PCB.
Our customer did design 2-Layer PCB and did test. But Device is dead…
Hi, Dino
1. The V3V and V7V can be used at same time, but the MAX current capability is only 10mA(see EC table in page6 of datasheet), they supply current to internal LV circuit, no recommend for external using.
2. Yes, you can use webench to simulate this…
Part Number: TPS65251 I have a set of boards with TPS65251 and I'm getting a periodic shutoff of the output with a clock frequency of ~1MHz.
It oscillates with no load. The soft start pin oscillates at 29.4Hz.
I am trying to drive 5V @ 2A on buck…
