1
All limits at temperature extremes are guaranteed via correlation using standard statistical quality control (SQC). Specifications are subject to change without notice.
2
Guaranteed by design, but not production tested. VIN can never exceed VOUT once the ADP1607 is enabled.
3
Minimum value is characterized by design. Maximum value is characterized on the bench.
4
This parameter is the semiconductor leakage current. The semiconductor leakage current doubles with every 10°C increase in temperature. The maximum limit
follows the same trend over temperature.
5
Thermal shutdown protection is only active in PWM mode.
