Product Details

The MAX77596 evaluation kit (EV kit) demonstrates the MAX77596 synchronous step-down converter IC with integrated switches. The EV kit operates over a wide input range of 3.5V to 24V and can support loads up to 300mA. The EV kit comes standard with the 3.3V fixed output voltage version of the IC. It can be easily modified to evaluate the 5V fixed output version or the adjustable output voltage version.

The EV kit includes jumpers to enable or disable the device, as well as to select either forced-PWM mode (FPWM) or skip-mode operation. A RESETB test point is available to monitor the voltage quality of the converter’s output.

Applications

  • Point-of-Load Applications
  • Portable Devices Powered from 2s, 3s, or 4s Li+ Batteries
  • USB Type-C Devices
