18-36 vin LMR16020 data sheet LM431 data sheet

The PMP15012 reference design is a DC/DC buck-boost solution which accepts an input voltage of 18 V to 36 V and provides a negative 15 V/200 mA output to the load. This reference design adds an external UVLO circuit to narrow the UVLO hysteresis because a buck-boost converter is difficult to shut down. This LMR16020 buck-boost reference design can be used for supplying the DAC/ADC/OA in an industrial application.
