TPS62237 - the description VOUT ≤ VIN –1 V on the datasheet P6

Hirotaka Matsumoto

Hi all

Would you mind if we ask TPS62237?

There is the description VOUT ≤ VIN –1 V on the datasheet P6.
Our cutomer's condition is as follows;

-Vin=3.6V to 4.2V
-Vout=3.3V
-Iout=0.2A

In this case, we can simulate using Webench.
Does it require 1V difference between Vin and Vout?Or in case of Min Vin(2.05V), does it require 1V difference?

Kind regards,

Hi Hirotaka-san,

for you specification doesn't require voltage difference 1V.
The description VOUT ≤ VIN –1 V is valid for maximum output current 500mA.

For maximum output current 350mA there is specification of the nominal value of the minimum supply voltage 2.5V and maximum value of the minimum supply voltage 2.7V.

The customer application is with minimum input voltage 3.6V which is above this limit.

Best regards
