Hi,all
Let me ask you some questions about TPS54519.
In the case of using two TPS54519 as Figure22 of datasheet, equation(5～8) is needed to calculate R1 and R2,however how should I calculate Vssoffset ? Vssoffset depends on a variability of resistors and Vref ?
Example, in the case of Vout1=1.15V ,Vout2=1.1V,Vssoffset=10mV,Iss=2.4uA,Vref=0.6V,according to equation(5)(6),R1 comes to approximately 8kΩ,R2 comes to approximately 9.6kΩ.And,Vss voltage comes to approximately 0.63V.
The sentence "The SS/TR pin voltage needs to be greater than 0.87 V for a complete handoff to the internal voltage reference as shown in Figure21" is written on datasheet P17,however if SS/TR pin is lower than 0.87V,is there a problem?
Best regards.
Taichi
