The MAX1702 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that demonstrates the MAX1702B power-management IC. The IC is optimized for microprocessor-based applications. The MAX1702B integrates three high-performance step-down DC-DC power supplies with associated supervisory and management functions. The first power supply (VI/O) is configured for 3.3V and provides up to 900mA. The second power supply (VCORE) is configured for 1.1V and provides up to 400mA. The third power supply (VMEM) can be configured to 1.8V, 2.5V, or 3.3V and provides up to 800mA. Power management functions include automatic power-up sequencing, power-on reset, manual reset with timer, and two levels of low-battery detection.

The EV kit operates with a 2.6V to 5.5V input voltage range, allowing the use of batteries or a regulated DC power supply at the input.
