Analog Devices / Maxim Integrated MAX17672CEVKIT Evaluation Kit
Analog Devices Inc. MAX17672CEVKIT Evaluation Kit is a fully assembled and tested circuit board that demonstrates the performance of the MAX17672C. The MAX17672C is a dual-output regulator integrating a high-efficiency, high voltage, adjustable output voltage, synchronous step-down DC-DC converter and a high-PSRR, low-noise, fixed-output linear regulator. The evaluation kit is designed for a balanced size and efficient solution. It generates a 5V step-down converter output voltage and a fixed 1.8V linear regulator output voltage at load currents up to 150mA and 50mA, respectively. When the linear regulator output is loaded, the step-down converter output current is reduced by ILDO, where ILDO is the load current on the linear regulator output in mA.
The evaluation kit draws only 120µA supply current under no-load conditions. The step-down converter is programmed to a switching frequency of 600kHz and delivers a peak efficiency of 90.2% with the supplied components. The dual-output device is simple to use and easily configurable with minimal external components. The evaluation kit features adjustable input undervoltage lockout, open-drain RESET signal, hysteretic peak current-limit protection, and external clock synchronization. The ADI MAX17672CEVKIT Evaluation Kit also provides a good layout example, optimized for conducted and radiated EMI.
