Product Details

The MAX17672CEVKIT# evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates the performance of the MAX17672C 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 EV kit is designed for a balanced size and efficiency solution and 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 EV 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 dualoutput device is simple to use and easily configurable with minimal external components. The EV kit features adjustable input undervoltage lockout, open-drain active-low RESET signal, hysteretic peak current-limit protection and external clock synchronization. The EV kit also provides a good layout example, which is optimized for conducted and radiated EMI. For more details about the IC benefits and features, refer to the MAX17672 IC data sheet
