Input requirements:
- Buck topology
- Input voltage: 3.5V – 8.5V protected and stabilized already
- Max efficiency
- Enable pin
- Power good – optional, but a benefit
- Solution can be found in one package or several bucks as follows:
- Two separate bucks, and one LDO
- One IC for double buck , and one LDO
- One IC for all three
In this board efficiency is the most important even if it means to have “bigger” solution.
Output requirements:
- 1.2V , 0.3A (max)
- 1.8V, 0.5A (max)
- 1.3, 10mA (LDO)
- Please advise best solution
