Description/Applications

The MAX17671F evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates the performance of the MAX17671F dual-output regulator integrating a high-efficiency, high voltage, fixed 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 high efficiency solution, and generates a 5V step-down converter output voltage and a fixed 3.3V 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 I_LDO, where I_LDO is the load current on the linear regulator output. The EV kit draws only 70μA supply current under no-load conditions. The step-down converter is programmed to a switching frequency of 200kHz and delivers a peak efficiency of 90% with the supplied components. The dual-output 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 frequency synchronization.
