Product Details

The MAX17552 5V evaluation kit (EV kit) (TDFN) is a fully assembled and tested circuit board that demonstrates the performance of the MAX17552 60V, 100mA ultra-small, high-efficiency, synchronous step-down DC-DC converter in a 10-pin TDFN package. The EV kit operates over a wide input-voltage range of 6V to 60V and provides up to 100mA 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 and delivers a peak efficiency of 93% with the supplied components. 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 MAX17552ATB+ in a 10-pin (3mm x 2mm) lead(Pb)-free/RoHS-compliant TDFN package.

Applications

  • 4–20mA Current-Loop Powered Sensors
  • Battery-Powered Equipment
  • General-Purpose Point-of-Load
  • High-Voltage LDO Replacement
  • HVAC and Building Control
  • Industrial Sensors and Process Control
