Evaluation Boards - Linear Voltage Regulators

Linear voltage regulators have the ability to convert one voltage to another voltage in a linearized fashion. The NCV3337MN500GEVB is an evaluation board that was designed to facilitate easy evaluation of the NCV3337 linear voltage regulators from ON Semiconductor. The evaluation board is capable of providing regulators from a 1.2V output down to a 0.6V output with a 1.2A current output.

NCP3337MN500GEVB Application Field 

The combination of the NCV3337MN500GEVB and the NCV3337 linear voltage regulator makes it ideal for applications such as embedded systems, digital video recorders, homes and home entertainment. The board and regulator also offer a great solution for providing current to large scale industrial applications like uninterrupted power supplies, inverters, and even sound systems.

NCP3337MN500GEVB Working Principle

The board works by having its input fed through an adjustable-voltage VDDIN version-compatible with the NCV3337 regulator. From the VDDIN, the board takes the voltage and adjusts it to match the output voltage. The output of the regulator is then controlled by two control signals: OVLO (overload) and EN (enable). The control signals open/close the physical switch that powers the output of the regulator.

The 0.6V to 1.2V adjustment is done with a resistor divider connected between the VDDIN and the output of the regulator. When the EN and OVLO pass the logic values, it will turn the switch on and the voltage will be regulated and provided to the target load. With OVLO being a combined thermal and current overload protection, it will shut down the circuit if those two conditions are met.

Conclusion

The NCV3337MN500GEVB evaluation board and linear voltage regulator from ON Semiconductor is a great way to quickly put a digital voltage regulator into projects. This board and regulator combo is a great fit for applications ranging from industrial and commercial power supplies to embedded systems and home audio systems. With its adjustable-input voltage and logic controlled adjustable output voltage, the board and regulator can be safely used for most systems.
