- Maximum input current at 3A output: Approximately 0.75A at 12V input, 0.6A at 15V input
- Output voltage: 3.3V (+2% -10%)
- Maximum output current: 3A
- Maximum Output Power: 9W
- Efficiency: >96%
- Size (L x W x H): 38 * 27 * 23 mm (Length including mounting tabs is 52mm)
- Weight: 30g
- Case color: White
- Cable length: 12cm (approx)
Operating Notes:
As with any DC-DC converter, the input DC power supply powering this converter must be capable of providing the maximum power drawn by your load. If the input supply is not capable of providing the power, the converter will fold back the output voltage as necessary. Example: If your load draws 3A at 3V (9W), and the input supply is only capable of providing 12V at 1/2A (6W), the maximum output voltage the converter will deliver is 2V (6W/3A).

I installed this step down in my camper to power my level mate pro that originally took a button cell battery. I’ve had it installed for over a year with no issues!
Used this to step down the power for my Ring Alarm Retrofit Kit. The retrofit panel that connects your existing sensors from a legacy wired alarm system to use Ring Alarm only runs on battery, I quickly found out that the legacy wired motion sensors quickly drained the battery on the retrofit kit and the battery was dead in a little over a month. I purchased this and wired it to the 12v power that is providing power to the old alarm panel and connected the other to the positive side of the battery terminal in the retro fit kit, now I don't have to worry about a separate battery as there is still a 12v backup battery in the old alarm panel in case of a power outage.
Used this to wire in a solar yard light purchased from the "Really" cheep tool store into my barn that is wired to 12 VDC with solar panels, also from the "Really" cheep tool store.No flicker from the ripple of the output that I can see.Don't have an O-Scope to measure for the ripple.12 VDC to 3 VDC the ripple would be minimal at worst.The real test will be how long will this last.Will give it 6 months.If fails in 6 months will update with more information.
This thing worked out great!I got a garage door opener for my motorcycle that was battery operated. It was awesome but the damn battery kept dying. Soldered some wire ends to the battery holder, tied them to this transformer, and wired it to my motorcycles battery. Works great & has been for a few months now
I used this device to convert a solar panel 12 vdc to 3 vdc and remove the batteries. Works well. Amazing what can be found on the internet.
