Frequently Asked Questions
What is the minimum input voltage the LTC3108EDE#PBF can harvest energy from, and what sources can deliver that level?
The LTC3108EDE#PBF can start and operate from input voltages as low as 20 mV. Practical sources that can supply this level include small thermoelectric generators (TEGs) mounted on warm pipes or machinery, indoor solar cells in low-light environments, and vibration energy harvesters. This makes the device suitable for self-powered industrial sensors requiring no battery maintenance over multi-year deployments.
Which regulated output voltages does the LTC3108EDE#PBF support, and how do I select among them?
The LTC3108EDE#PBF supports four selectable output voltages: 2.35V, 3.3V, 4.1V, and 5V, chosen via two external logic pins (VSEL0 and VSEL1). The 3.3V setting is most commonly used for microcontrollers and Bluetooth Low Energy transceivers, while 5V suits sensors with legacy analog interfaces. All four options are available with the same 12-pin DFN footprint.
How does the 12-pin DFN package of the LTC3108EDE#PBF compare to SOIC alternatives for thermal and board-area considerations?
The 12-pin DFN (3 mm × 4 mm) occupies roughly 12 mm² of board area, about 60% less than a comparable 12-pin SOIC footprint. The exposed thermal pad on the DFN bottom improves heat dissipation during peak conversion bursts, keeping junction temperature well below the 125°C maximum rating even in compact enclosures. This makes it the preferred choice when PCB space is at a premium in sealed sensor housings.
