Download Reference Design DocumentThe Reference Design Document describes the hardware pictured below. It provides a detailed systematic technical guide to designing a boost, single-output, DC-DC converter, 1V to 3.3V input, 13.5V/6mA output. The hardware was built according to the linked Schematic, Bill of Materials and PCB Artwork. It was tested by Maxim’s expert applications engineering team in a state-of-the-art design lab and the Test Results are fully documented. Downloadable ECAD/EDA files are available in 7 different formats including OrCAD, Altium, Mentor DX Designer, Eagle and more.

The MAX1606 is a step-up DC-DC converter that contains a 0.5A internal power switch and a 0.5A output isolation switch in an 8-pin µMAX® package. The IC operates from a 2.4V to 5.5V supply voltage but can boost battery voltages as low as 0.8V up to 28V. The MAX1606 uses a unique control scheme that provides high efficiency over a wide range of load conditions. An internal 0.5A MOSFET reduces external component count, and a high switching frequency (up to 500kHz) allows for tiny surface-mount components. The current limit can be set to 500mA, 250mA, or 125mA, allowing the user to reduce the output ripple and component size in low-current applications. Additional features include a low quiescent supply current and a true shutdown mode that saves power by disconnecting the output from the input. The MAX1606 is ideal for small LCD panels with low current requirements, but can also be used in other applications.
A single-output boost converter using the MAX1606 is demonstrated for a 1V to 3.3V input voltage range. The output is configured to be equal to 13.5V. The power supply delivers up to 6mA at 13.5V with up to 4% output voltage regulation at 1V.
