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 under 75%.
