DC-DC step-up converter:
no-iron converter for mobile charging of low-power battery packs
The voltage step-up converter described in this article is a transformerless design based on just one integrated circuit and a handful of passive parts. Efficiency is excellent given the simplicity of the circuit, which requires no modifications for any input voltage between 6 V and 12 V, for output voltages of about 10 V and 22 V respectively.
