Simplified Schematic Block Diagram Table 1. PIN FUNCTION DESCRIPTION DFN10 Pin No. Pin Name Description 1 GND Power supply ground. Soldered to the copper plane allows for effective heat dissipation. 2 OUT1 Regulated output voltage of the first channel. A small 1 F ceramic capacitor is needed from this pin to ground to assure stability. 3 OUT2 Regulated output voltage of the second channel. A small 1 F ceramic capacitor is needed from this pin to ground to assure stability. 4 GND Power supply ground. Soldered to the copper plane allows for effective heat dissipation. 5,6 N/C Not connected, can be tied to ground plane to improve thermal dissipation. 7 EN2 Driving EN2 over 0.9 V turns-on OUT2. Driving EN below 0.4 V turns-off the OUT2 and activates the active discharge. 8 IN2 Inputs pin for second channel. It is recommended to connect 1 F ceramic capacitor close to the device pin. 9 IN1 Inputs pin for first channel. It is recommended to connect 1 F ceramic capacitor close to the device pin. 10 EN1 Driving EN1 over 0.9 V turns-on OUT1. Driving EN below 0.4 V turns-off the OUT1 and activates the active discharge. EXP Exposed pad must be tied to ground. Soldered to the copper plane allows for effective thermal dissipation. www.onsemi.com 2
