(1)

Minimum and maximum limits are 100% production tested at 25°C. Limits over the operating temperature range are verified through

correlation using Statistical Quality Control (SQC) methods. Limits are used to calculate Average Outgoing Quality Level (AOQL).

(2)

This is the input voltage at which the device starts to operate (rising). The device shuts down when the input voltage goes below this

value minus the hysteresis.

(3)

This is the current used by the device, open loop. It does not represent the total input current of the system when in regulation. See

Isupply in System Characteristics

(4)

The FB pin is set to 5.5 V for this test.

(5)

Below this voltage on the EN input, the device shuts down completely.

(6)

See the Current Limit section for an explanation of valley current limit.

7.5 Electrical Characteristics

Limits apply to the recommended operating junction temperature range of –40°C to 150°C, unless otherwise noted. Minimum

and maximum limits are verified through test, design, or statistical correlation. Typical values represent the most likely

parametric norm at TJ = 25°C, and are provided for reference purposes only. Unless otherwise stated the following conditions

apply: VIN = 13.5 V.
