MAX1703 Single-Cell Boost Converter Circuit

When you design a circuit with only a single-cell battery, you will need boost-converter to provide enough voltage for most application. This circuit is a modification of the diode-OR connection circuit. The linear regulator is formed by the U1’s internal gain coupled with the PFET(Q1). The diode-OR connection is connected to Q1’s source that will act as USB power supply. […]

Transformerless Dc -To- Symmetric DC Converter

A DC to DC converter is needed for a board that only has +5V supply but have to provide dual-polarity supplies for few device such as op-amp or some DAC. Using switched capacitors as the main converting element (diode-capacitor voltage-doubler), there is no inductors or transformers in this circuit. This circuit also does not require dc-to-dc converter ICs but uses […]
