TPS74801: Vout range limitation of 3.6V

Shinya Sawamoto

Part Number: TPS74801
Other Parts Discussed in Thread: TPS7A92,

Hello,

What is the reason for the limitation of 3.6V Vout max in TPS748? (ABS max looks allow up to Vin+0.3V)
If we use with Vout>3.6V, what could it happen? (for example, Vin=4.5V & Vout=4.2V)

Thanks in advance.

Hi Shinya,

An output voltage of 4.2 V is beyond the range where TPS74801 was designed, characterized, and tested to be operating. Please consider TPS7A92 which was designed, tested, and characterized for your application conditions.

Very Respectfully,
Ryan

Thanks Ryan,
I got understood that the limitation comes from not device quality reason but characterization coverage reason.
