Notes:

(1) Specification refers to application circuit.

(2) The soft start pin sources 25µA to an external capacitor. The converter operates in synchronous mode above the soft

start transition threshold and in asynchronous mode below it.

(3) Power good is an open collector pulled low when the output voltage is outside the ±10% window.

(4) This device is ESD sensitive. Use of standard ESD handling precautions is required.

(5) 200ns maximum at 75

°.

Unless Specified: V
