12V Step-Up DC-DC Converter from 1.8V to 5V Input

This is a DC/DC converter that combines a traditional voltage feedback loop and a unique current feedback loop to operate as a constant-current, constant-voltage source. The project has been designed using the LT1618 chip. The board provides 12V/150mA output, from input supply 1.8V to 5V_DC. The LT1618 uses a constant frequency, current mode control scheme to provide excellent line and load regulation.
