PMIC (power management integrated circuits) are highly integrated circuits that simplify power distribution and improve system efficiency. AC DC converters, Offline Switchers and other PMICs are important components that regulate and regulate the power supply of cameras, system boards and other electronic products. The NCP1079AAP100G is an AC/DC converter with a synchronous rectification buck topology. It is suitable for a range of applications such as in point-of-load (POL) regulators, personal computers and networking equipment, low power microprocessor, battery charging and telecom/personal media players.

Working Principle of NCP1079AAP100G

The NCP1079AAP100G is a two-phase interleaved synchronous step-down DC/DC converter with integrated current sensing circuitry. The two-phase interleaving provides an input voltage ripple of <= 0.06V at up to 500kHz for each phase, which is essential for efficient DC/DC converter performance. It also eliminates the need for an output capacitor, thus reducing overall system cost. The converter operates from an input voltage of 2.5V to 16V and is capable of providing an output voltage of up to 0.6V with up to 1A of continuous output current.

The synchronous rectification buck topology of the converter utilizes integrated power MOSFETs to achieve high efficiency operation. The switch node is regulated by the controller, which compares the feedback voltage at the FB pin to the internal reference voltage. The voltage is then fed to the Gate Driver to regulate the output voltage. Soft-start and over-current protection are also integrated on the controller.

NCP1079AAP100G Application Field

The NCP1079AAP100G is suitable for a range of applications that require low power, highly efficient solutions. Its high power density design makes it suitable for small form-factor products. Its features include low operating current and a wide range of input voltage, making it suitable for both portable and desktop electronic products. Furthermore, its integrated current sensing enables precise current limiting, thus protecting sensitive loads.

The NCP1079AAP100G is well suited to applications that require excellent power density, such as laptops and gaming consoles. It can be used in a number of applications where a wide input voltage range is required, such as personal portable media players and chargers. Additionally, it can be used as an alternative to POL regulators for applications that require a low output voltage, such as telecom systems, Wi-Fi transceivers, and Ethernet transceivers.

Conclusion

The NCP1079AAP100G is an efficient two-phase interleaved synchronous rectification buck topology converter with an integrated current sense circuitry. Its features make it well suited to a wide range of applications where low power, high power density and wide input voltage range is required. With its integrated over-current protection, it is also able to protect sensitive loads.
