Description

The PMP15012 reference design is a DC/DC buck-boost solution which accepts an input voltage of 18V to 36V and provides negative 15V/200mA 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.

Features
  • 18V to 36V Wide Vin 15V negative output
  • External UVLO circuit to narrow the buck-boost UVLO hysteresis
  • Peak current mode control
  • OCP for transformer saturation protection
  • Internal compensation for easy of use
