Simplified Schematic Block Diagram PIN FUNCTION DESCRIPTION Pin No. Pin XDFN6 Name Description 1 OUT1 Regulated output voltage of the first channel. A small 0.22 F ceramic capacitor is needed from this pin to ground to assure stability. 2 OUT2 Regulated output voltage of the second channel. A small 0.22 F ceramic capacitor is needed from this pin to ground to assure stability. 3 GND Power supply ground. Soldered to the copper plane allows for effective heat dissipation. 4 EN2 Driving EN2 over 0.9 V turnson OUT2. Driving EN below 0.4 V turnsoff the OUT2 and activates the active discharge. 5 IN Input pin common for both channels. It is recommended to connect 0.22 F ceramic capacitor close to the device pin. 6 EN1 Driving EN1 over 0.9 V turnson OUT1. Driving EN below 0.4 V turnsoff the OUT1 and activates the active discharge. EP Exposed pad must be tied to ground. Soldered to the copper plane allows for effective thermal dissipation. www.onsemi.com 2
