LM22679EVAL
概要
The LM22679 evaluation board is designed to demonstrate the capabilities of the LM22679 switching regulator. The LM22679 evaluation board is configured to provide an output voltage of 3.3V up to 5A load current with an input voltage range of 4.5V to 42V. Due to the low RDS(ON) of the integrated N-channel MOSFET and maximum duty-cycle limitations, the minimum input voltage of 4.5V will only provide a 3.3V output voltage for load currents up to 500 mA. At 5.5V input voltage 3A of output current is possible while maintaining 3.3V of output voltage. For load currents higher than 3A, in input voltage of 6.5V or higher is required. The typical operating frequency is 500 kHz. The evaluation board is designed to operate at ambient temperatures up to 30 °C.
特長
- Input Range: 4.5V to 42V
- Output Voltage: 3.3V
- Output Current Range: 0A to 5A

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 LM22679 switching regulator, the evaluation board can be re-configured for different output voltages.
