MAX17672CEVKIT#

MAX17672CEVKIT# is an evaluation kit designed to demonstrate the performance of the MAX17672C dual-output regulator, which integrates a high-efficiency, high-voltage synchronous step-down DC-DC converter and a high-PSRR, low-noise linear regulator. The EV kit is designed for a balanced size and efficiency solution and generates a 5V step-down converter output and a fixed 1.8V linear regulator output with continuous load currents up to 150mA and 50mA, respectively. When the linear regulator output is loaded, the available step-down converter output current is reduced by the LDO load current. Additional features include adjustable input undervoltage lockout, open-drain (active low)RESET output, hysteretic peak current-limit protection, MODE/SYNC control for PWM or PFM operation, and external clock synchronization. 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 for the step-down converter
• Peak efficiency of 90.2% for the step-down converter
• 120µA no-load supply current, 600kHz switching frequency
• Internal soft-start
• EN/UVLO input, resistor-programmable UVLO threshold
• Overcurrent and overtemperature protection
• Proven PCB layout
• Fully assembled and tested
• Complies with CISPR22 (EN55022) Class B conducted and radiated emissions
