You rely on datasheets for a good sense of how the IC will perform, but when it’s time for more of a “how to” lesson, that’s when reference designs come in handy. Maxim’s Reference Design Center features design implementations spanning single parts to subsystems and full system designs. Each of these designs was built and tested by our engineers.
Here’s a look at some of the newest additions to the Reference Design Center:
MAXREFDES1199: Build a Low-Cost Buck DC-DC Converter
This two-layer board demonstrates how to build a low-cost buck DC-DC converter using the MAX17244 high-efficiency, synchronous step-down converter for 5V DC output applications from a 12V to 32V input. The MAX17244 has integrated MOSFETS and operates over a 3.5V to 36V input voltage range with 42V input transient protection. The device uses a current-mode control architecture and can operate in the pulse-width modulation (PWM) or pulse-frequency modulation (PFM) control schemes. The reference design reduces costs with its minimized component count.

MAXREFDES1049: DC-DC Buck Power Supply
With this reference design, you can learn how the MAX17504 high-efficiency, high-voltage, synchronously rectified step-down converter can be used to generate 5V from an input voltage of 7.5V to 60V. The design is also intended for equipment that needs to pass electromagnetic interference (EMI) compliance testing, so you’ll gain an understanding of how to achieve high EMI performance using a proper filter with good PCB layout and shielding techniques. (This reference design has passed the conducted emission (CE) test of CISPR 22 class B.)
MAXREFDES1049 is a DC-DC buck power supply designed for equipment that needs to pass EMI compliance testing.
MAXREFDES1160: Build an Isolated RS-485 Module
This reference design provides a 5V supplied, 2.75kVRMS, full-duplex, and 500kbps isolated RS-485 module using the MAX14853 isolated RS-485/RS-422 transceiver. You can use this design to learn how to build an isolated RS-485 module with a low-cost transformer to provide isolated power. The design’s power supply comes from a single 5V source.

MAXREFDES1044: Heart-Rate Monitor
This reference design demonstrates how to implement a small, low-cost, low-power, high-accuracy heart-rate monitor. The design features the MAX30101 integrated pulse oximetry and heart-rate monitor module, which includes internal LEDs, photodetectors, optical elements, and low-noise electronics with ambient light rejection. The design also includes two MAX8892 high-PSRR, low-dropout, 150mA linear regulators, a MAX1555 single-cell lithium-ion battery charger, two MAX40200 ideal diode current switches, and a MAX6864 nanoPower µP supervisory circuit. Heart rate can be monitored with red, infrared, or green LEDs.
MAXREFDES1044 demonstrates the implementation of a small, low-power, highly accurate heart-rate monitor using the MAX30101 integrated pulse oximetry and heart-rate monitor module and other components.
MAXREFDES1215: Supercapacitor-Based Energy Harvester
This reference design demonstrates a supercapacitor-based energy harvester. The first stage of the circuit charges a supercapacitor, while the second stage regulates the voltage from the supercapacitor to supply various sensors with a steady output voltage. The MAX17220 ultra-low quiescent current boost DC-DC converter regulates the output voltage from the supercapacitor. Since supercapacitors are becoming more common in applications like electric vehicles, industrial machinery, and utility grids, this reference design provides a good head start.

MAXREFDES1204: Single-Output SEPIC Converter
This reference design, developed with the MAX16990 current-mode controller, demonstrates a single-output SEPIC converter. Targeted for automotive applications, this design is rated to operate over a wide input voltage range from 6V to 18V, and can deliver an output power of 24W at 12V.
MAXREFDES1204 demonstrates very high efficiency (> 90% for load > 25%), very low line and load regulation (< 0.02%), and continuous conduction mode operation.
