Question regarding to PTN78020A
I want -17V output, do you have power module similar as PTN78020A to
There is no -17V inverter power module from a (+) input power source. The maximum inverter voltage from the PTN78N series is -15V with maximum +input voltage of 17V.
One suggestion is to use the TPS54240 (Page 40) or TPS54260 swift IC for inverting the output voltage along with SLVA317a application note
May I do the same thing to TPS5450?
It appears the TPS54240 is newer swift IC. The question on whether to use the TPS5450 ro TPS54240/260 for -17V should sent to the SWIFT group.
I appears the TPS54240 is rated to 2.5A and the TPS5450 is rated to 5Amps .
The other factors to be considered in the (-) configuration is the maximum power capability.
