Working Principle
NCP1530DM30R2 DC-DC buck switching regulator works by converting a higher voltage input source like a battery or power supply down to a lower and more stable output voltage. The NCP1530DM30R2 operates in a buck converter configuration wherein the output voltage is always lower than the input voltage. The NCP1530DM30R2 uses high-speed integrated MOSFETs with a fixed switching frequency of 1.5MHz to reduce EMI and harmonic content in the output. The high switching frequency also improves power stage efficiency. A control loop regulates the output voltage by adjusting the duty cycle of the internal power MOSFETs. The step-down DC-DC switching regulator provides fast transient response and excellent thermal performance by using a combination of low on-resistance and fast switching speed.Conclusion
The NCP1530DM30R2 is a integrated DC-DC buck switching regulator with a wide input voltage range and low quiescent current.
