TPS65124: How can we simulate the design of TPS65124?

Hello,

Input voltage range of 3V to 4.3V is not a problem for this device. TPS65124 has positive source voltage VMAIN (range 3V-5.6V), and bipolar gate voltages VGH/VGL. These three voltages can be set using the feedback resistor divider as explained in the datasheet section "Setting the output voltage" (also copied below). Other capacitors/Inductors values should be chosen as shown in figure 22 in the datasheet.

Kind Regards,

Hello and thank you for the post again. I searched and, unfortunately, we do not have a simulation model available for this older device.

Hello again,

I see your application requirements as:

input range: 3V to 4.3V

positive voltage output range: 3V to 6V

negative voltage output range: -5V to -10V

So the requirement is for a split rail (+/- output) supply in the range given. I do not see another device that can exactly meet the voltage ranges you outlined but two possible split rail devices to consider are TPS65131 and TPS65132. Their datasheets are available online.

You are welcome.
