TYPICAL PERFORMANCE CHARACTERISTICS
VIN = VENx = 5.0 V, CIN1 = CIN2 = COUT1 = COUT2 = 10 µF (GRM21BR61C106KE15), L1 = L2 = 2.2 μH (XFL3012-222MEB), typical values are
at TA = 25°C, and minimum/maximum limits are guaranteed for TJ = −40°C to +125°C, unless otherwise noted. All limits at temperature
extremes are guaranteed via correlation using standard statistical quality control (SQC).
