Working Principle

The NCV885300D1R2G Dual 40V DC-DC Controller utilizes a synchronous buck topology, which uses a high-frequency oscillator and two P-Channel MOSFETs to switch the voltage in two steps, allowing for very high efficiency. The integrated low side and high side MOSFETs are optimized to provide low switching on-resistance, while meeting tight service loop requirements.

The voltage is controlled by an external resistor and a feedback pin. The feedback pin senses the output voltage and determines when to switch on or off the MOSFETs, thereby regulating the output voltage. The controller also features an adjustable current limit, which prevents damage to the MOSFETs, as well as a thermal shutdown protection which shuts down the MOSFETs when the temperature exceeds a certain threshold to protect the device from damage.

The NCV885300D1R2G Dual 40V DC-DC Controller also offers power saving modes, allowing the device to be operated at lower power consumption when in idle mode, ensuring the device remains efficient even during low load. Finally, the integrated power-saving mode allows for efficient operation in standby mode, reducing power consumption to 2µA.

Conclusion

The NCV885300D1R2G Dual 40V DC-DC Controller by On Semi is a high-performance and efficient device, suitable for a wide array of applications. Featuring integrated low side and high side MOSFETs, current limit and thermal shutdown protection, as well as power saving modes, the NCV885300D1R2G is an excellent choice for advanced power regulation.
