Buck ldo boost
Did you know?
WebMay 9, 2024 · Also, while an LDO can only regulate down (buck), there are buck, boost, and even buck/boost switchers with seamless transition between the two modes. That’s an important capability, as many circuits operate from a single Li-ion cell and need buck/boost mode to regulate the battery from fully charged down to somewhat discharged. WebIn your place, I would either: 1. Use an LDO if there is not really a need to optimize for battery life time. 2. Find a buck-boost regulator already soldered to a small PCB with all the external components. You can get something like that on eBay. Just be sure to check the various requirement, like voltages and output current.
