  Hi Jerry, EN is not recommend to directly connected with Vin. You can refer to a reference design www.ti.com/.../TIDA-050053 for more details about how to design EN level shifter circuit. For other curcuits, I am also reviewing now. Thanks BRs Lucia

  Hi Jerry! Second SH is wrong. If you want a negative output, you can use buck converter to construct a buck-boost converter. www.ti.com/.../TIDA-050053 Shuai

  Hi Francis! This device can support negative output. But your SCH need to add some external device to achieve the UVLO. Pls refer this reference design. https://www.ti.com/tool/TIDA-050053 Shuai

  Hi Steve I am sorry for that we don't have the pspice model for the inverting buck boot operation. Actually we have some reference designs for the inverting buck boost operation using other devices, may be you can refer to that. Link: https://www.ti…
