Overview

The LM22670 inverting evaluation board is designed to demonstrate the capabilities of the LM22670 switching regulator in a polarity inverting topology. The LM22670 inverting evaluation board is configured to provide an output of minus 5V (-5V) up to 1.5A load current with an input voltage range of 5V to 35V. The typical operating frequency if 500 kHz. evaluation board is configured to provide an output voltage of 3.3V up to 500 mA load current with an input voltage range of 4.5V to 42V. The typical operating frequency is 500 kHz.

The evaluation board is designed to operate at ambient temperatures up to 50 °C. To aid in the design and evaluation of DC/DC polarity-inverting converter solutions based on the LM22670 switching
