LTC3108
Recommended for New Designs
The LTC3108 is a highly integrated DC/DC converter ideal for harvesting and managing surplus energy from extremely low input voltage sources such as TEGs...

Hello,
Is it possible for one of your voltage step-up products to cold start/operate from ultra low Vin, like your LTC3108, but instead of using transformers/inductors, that the product be entirely switched capacitor based? Your LTC1502-3.3 is switched capacitor based, but only operates down to Vmin=0.9V. If there aren't any existing products that can be "hacked" for this purpose, is this technically feasible for future products?
The low voltage operation of LTC3108 is excellent, but I'm interested in operation without inductors.
Thank you
Mark
Hi Mark
Unfortunately, we do not have inductorless converters that operate at very low input voltage. Since charge pumps stack voltages to boost the output voltage, it is difficult to effectively create ultralow input voltage charge pumps.
