Note 1: Absolute Maximum Ra�ngs are those values beyond which the life of a device may be impaired.

Note 2: TJ is calculated from the ambient temperature TA and power dissipa�on PD according to the

following formula: TJ = TA + PD x θJA.

Note:

To exactly iden�fy the short circuit characteris�c of IC, avoid the test result interfered by parasi�c inductor,

output capacitor, and contact resistor. It is necessary to follow the recommenda�on as follows.

1. Add 1000μF of capacitor between VIN and GND, and close to IC.

2. Remove output capacitor.

3. Shorter the short circuit device wire.

4. Measure output current (IOUT).
