Part Number: TPS51916 Hi,
I'm using TP51916 on a new design with DDR3.
At startup, PGOOD is pulsing high, 1.2ms, then goes low as captured below.
As PGOOD is controling the board reset, the complete board is held in reset.
The output voltage is…
Part Number: TPS51916 How to contorl TPS51916's power-up ,because we use it power our cpu at the same time, but our cpu has a power-up sequence.
thanks very much!
