Product Details

The MAX1951 evaluation kit (EV kit) provides a 1.5V output voltage from a 2.6V to 5.5V input source.The output voltage can be adjusted from 0.8V to VIN. The MAX1951 delivers up to 1.5A output current. The MAX1951 is a fixed-frequency, pulse-width modulated (PWM) step-down switching regulator with internal synchronous-rectifier. Operation at 1MHz minimizes external components.

The MAX1951 EV kit can also be used to evaluate other output voltages by changing the feedback resistors R2 and R3. The EV kit can also be used to evaluate the MAX1952, which is a 1.5A PWM step-down switching regulator with a 1.8V fixed output voltage.
