The MAX1626 evaluation kit (EV kit) provides a selectable 3.3V or 5V output voltage. The MAX1626 has a high-switch duty cycle of up to 100%, allowing the external P-channel transistor to turn on fully. The 100% duty cycle and a low 100mV current-sense level permit very low dropout voltages. The circuit is configured to deliver up to 2A of output current with greater than 90% conversion efficiency.
This EV kit is a fully assembled and tested surface-mount circuit board. It can also be used to evaluate the MAX1627, which has an adjustable output voltage. Additional pads on the bottom of the board accommodate the external feedback resistors for setting different output voltages.
