The ISL6273EVAL1 evaluation board provides a convenient platform to evaluate the performance of the ISL6273 low quiescent high-efficiency step-down switching regulator. The ISL6273 is a 1.5MHz, 1.2A adjustable output voltage regulator. The output voltage is set by a resistor divider consisting of R1 and R2 on the board. The output voltage is set to 1.6V on the evaluation board but can be modified by changing the R2 value. The evaluation board also allows users to evaluate the forced PWM or PFM operation mode at light load and the behavior of the POR signal.
