Dear Team
May I know if TI have any suitable solution, either device or reference design, for the following spec?
Input voltage: -34V to -60V range
Output voltage: 12V
Output current: 0.6A
Many thanks
Denny
Hi Denny,
Thank you for reaching out. Yes this can be supported by a boost controller or converter in the inverting buck-boost configuration like shown in the following ref design:
https://www.ti.com/tool/PMP20371
Obviously the ref design has a much higher power than you need, and the components can be scaled down. You may submit a ref design request to the PDS group.
Thanks,
Youhao
Hi Youhao
Sorry, The output voltage is 54V, dose pmp20371 is suitable for the spec?
Input voltage: -34V to -60V range
Output voltage: 54V
Output current: 0.6A
Many thanks
Denny
Hi Denny,
If the output is 54V, the SW voltage is more than 114V, so LM5122 can't handle such high voltage.
This output power is not large, it is recommended to use the non-synchronous scheme. you can check LM5156.
