MAX17670EEVKIT#

MAX17670EEVKIT# is a MAX17670E evaluation kit (EV kit), which is a fully assembled and tested circuit board that demonstrates the performance of the MAX17670E 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. The EV kit generates a 3.3V step-down converter output voltage and a fixed 3V linear regulator output voltage at load currents up to 150mA and 20mA, respectively. When the linear regulator output is loaded, the Stepdown converter output current is reduced by ILDO, where ILDO is the load current on the linear regulator output. The EV kit draws only 70µA supply current under no-load conditions. The dual-output device is simple to use and easily configurable with minimal external components.

• 4.5V to 60V input-voltage range for the step-down converter
• Peak efficiency of 90.6% for the step-down converter
• 70µA no-load supply current
• 200kHz switching frequency and external frequency synchronization
• 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
• Overcurrent and overtemperature protection
• Proven PCB layout, fully assembled and tested
