描述

The MAX731 evaluation kit (EV kit) facilitates assembly and evaluation of Maxim's MAX731 +5V step-up current-mode DC-DC converter.

The EV kit includes all needed components (unassembled) and a printed circuit board. When completed, the EV kit is a working DC-DC step-up converter with +5V output voltage at 200mA.

Typical full-load efficiencies are 82% to 87%. The MAX731 uses current-mode pulse-width modulation (PWM) to provide precise output regulation and low subharmonic noise. Typical no-load supply current is 2mA.

The MAX731 features cycle-by-cycle current limiting, overcurrent limiting, external shutdown, and programmable soft-start protection.

The EV kit components are suitable for through-hole mounting to make construction and evaluation easy. Refer to the MAX731 data sheet for detailed electrical and operating specifications.
