All limits at temperature extremes are guaranteed via correlation using standard statistical quality control (SQC). Typical values are at T
This is the V
This is the current into the V
INTF should be tied to GND (INTF = 0) for I
This bias current is active only when the high power LED and/or indicator LED functions are enabled.
This specification is not valid during minimum on-time operation of the boost converter (one LED case) when excess voltage is dropped across the HPLED pin.
This specification is not production tested but is based on bench evaluation. It is based on the typical two-LED application circuit using a 100 kΩ resistor from SETF to GND,
and a 160 kΩ resistor to a 1.8 V Tx mask logic signal with <1 μs rise/fall time. HPLED register = 11001 (binary). The inductor current has settled to within ±5% of final value.
