The LM22671 evaluation board is designed to demonstrate the capabilities of the LM22671switching regulator. The LM22671 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.
At low input voltages between 4.5V and 6V, a minimum load of approximately 5 mA may be required to reach a regulated 3.3V output voltage.
To aid in the design and evaluation of DC/DC buck converter solutions based on the LM22671 switching regulator, the evaluation board can be re-configured for different output voltages.
