This specification is not tested in production.

The ADPL74101 is tested in a feedback loop that servos VITH to a specified voltage and measures the resultant

VFB.

SENSE− bias current is reflected to the input supply by the formula IVIN = ISENSE− × VOUT/(VIN × η), where η is the

efficiency.

Rise and fall times are measured using 10% and 90% levels. Delay times are measured using 50% levels.

The minimum on-time condition specified for inductor peak-to-peak ripple current is >40% of the maximum

load current (IMAX). See the Minimum On-Time Considerations section for more details.
