    Description

    MAX1972EVKIT evaluation kit (EV kit) is a fully assembled and tested circuit board that evaluates the MAX1970 family of dual step-down regulators. The circuit operates from an input voltage of 2.6V to 5.5V, and delivers a minimum of 750mA on each output. The output voltages are programmable from 0.8V to VIN using external feedback resistors, or they can be preset to 3.3V or 1.8V for output 1, and 2.5V or 1.5V for output 2. The board has a MAX1972 installed, but it can also be used to evaluate the MAX1970 and the MAX1971. The MAX1971 features a reset input (RSI), while the MAX1970/MAX1972 feature a power-fail output (PFO).
