Product Details

The MAX8625A evaluation kit (EV kit) is a fully assembled and tested PCB demonstrating the MAX8625A step-up/step-down switching regulator. The MAX8625A utilizes Maxim's proprietary H-bridge topology that provides seamless transitions through all converter operating modes without the glitches commonly seen with other similar devices. The MAX8625A EV kit converts a 2.5V to 5.5V DC input to a preprogrammed 3.3V output capable of providing up to 800mA. The output voltage is also programmable from 1.25V to 4.2V by use of a resistor-divider. The MAX8625A EV kit provides on-board jumper settings that allow programming one of two switching modes: fixed-frequency PWM (FPWM) or high-efficiency skip. Additional on-board jumpers allow enable or shutdown of the MAX8625A IC.
