boost converter won't boost high enough
|Assignee:||Andrew Kohlsmith||% Done:|
The TLV61220 has a maximum output voltage of 5V. We need about 16V.
There aren’t many SOT23 boost regulators which will go that high, but there are a fair number of LED drivers. Guess what we’re doing with this supply?
- TPS61165: $3 in singles
- FAN5345: $1.50
- AP5725: $0.84
- AP3032: $0.77
- AP3602: $0.66, not dimmable
- AHK1421: $0.64, goofy serial protocol to dim
Generally speaking the cheaper you get the goofier you get. We don’t need much current so the cheapies will work fine. They all seem to share more or less compatible pinouts as well.
