Product Details

The MAX17530 5V evaluation kit (EV kit) (µMAX) is a fully assembled and tested circuit board that demonstrates the performance of the 42V, 25mA ultra-small, high-efficiency, synchronous step-down DC-DC converter in a 10-pin µMAX package. The EV kit operates over a wide input voltage range of 6V to 42V and provides up to 25mA load current at 5V output. It draws only 26µA supply current under no-load conditions (EN/UVLO connected to VIN). The EV kit is programmed to switch at a frequency of 220kHz. The device is simple to use and easily configurable with minimal external components. It features cycle-by-cycle peak current-limit protection, undervoltage lockout, and thermal shutdown.

The EV kit comes installed with the MAX17530AUB+ in a 10-pin (3mm x 3mm) lead (Pb)-free/RoHS-compliant µMAX package.

Applications

  • Battery-Powered Equipment
  • High-Voltage LDO Replacement
  • HVAC and Building Control
  • Industrial Sensors and Process Control
