MAX17671FEVKIT#

Evaluation kit for the MAX17671 5V step-down converter and 3.3V linear regulator output voltage application. This 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. The EV kit features adjustable input undervoltage lockout, open-drain active-low RESET signal, hysteretic peak current-limit protection and external frequency synchronization. It is suitable for battery-powered equipment, high-voltage linear regulator replacement, HVAC and building control, industrial sensors and process control applications.

• 6.5V to 60V input-voltage range and peak efficiency of 90% for the step-down converter
• 70µA no-load supply current, 200KHz switching frequency
• Internal soft-start
• EN/UVLO input, resistor-programmable UVLO threshold
• MODE/SYNC pin to select PWM or PFM mode
• Open-drain active-low RESET output to monitor dual outputs
• External frequency synchronization
• Overcurrent and overtemperature protection
