2.2 Operation

Connect a valid VBIAS voltage, between 2.5V and 5.5V to J1 or TP5. Using a combination of J1, J2, J3, J6, and J7, select and apply valid VINx voltages, between 0.6V and VBIAS to VIN1 and VIN2. For instance, VIN1 = VBIAS = VSUP1 and VIN2 = VSUP2, connect shunts between the leftmost pins of J6 and the middle pins of J7.

To adjust the output slew rate upon enable, use SW1/SW2 to connect different equivalent resistor values between VON1/VON2 and ON1/ON2, respectively. The slew rate can be calculated using Equation 1 and Table 9-1 of the TPS22996 data sheet.

External loads can be connected to J10 and J12. When the ON pin is toggled high, the device connects VINx to VOUTx with the slew rate previously referenced.
