Part Number: TPS54226 Hi Experts
our customer find switching frequency have jitter. datasheet is 700kHz but when they use long time .
frequency maximum value would be 1.397Mhz and minimum is 353.3kHz.
customer have four question want…
Part Number: TPS54226 Hi Team,
One quick question.
What is the status of the PG output when EN is set to low (device disable condition)?
Regards,

Part Number: TPS54226 Hi
Because the MOSFET are in the converter, the spec only show the SW(low side MOSFET) max voltage=20V.
We want to know the high side MOSFET max voltage=?
Thank you!
Hi Max,
As Jason mentioned, the device is under overcurrent protection and Vout could not establish. The device will enter into hiccup mode if output is is undervoltage. This is a 2A device.

Other Parts Discussed in Thread: TPS54226 Hi Team,
Our customer would like to know whether TPS54226 can change the output voltage by the external DAC.
I understand that this method is common for current mode DC-DC.
So, can I use this method to…
