1.3.2 Device Evaluation

Components JP1 can be populated to evaluate the device enable feature of this IC. When JP1 is connected to HIGH, IC is enabled and be disabled when JP1 connected to LOW.

Components JP2 can be populated to evaluate the device FPWM/PFM feature of this IC. When JP2 is connected to HIGH, IC works in FPWM, with smaller output ripple but lower efficiency in light load. Otherwise, IC works in PFM mode, with bigger output ripple and better efficiency in light load.
