NOTES:

(1) All electrical characteristics are for the application circuit on page 1.

(2) Soft start functionality is performed along with short circuit protection. If V

switches are turned off and V

200mV all switches are enabled.

(3) Guaranteed by design.

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

(5) The internal switch resistance, the capacitor ESR and the Oscillator’s switching frequency all contribute to
