NCP1060AD060R2G Application Field and Working Principle

PMIC or Power Management Integrated Circuit are used to control and store electricity. A particular type of PMICs are AC to DC (A/C) Converters, Offline Switchers, which convert household current from single-phase AC to DC power. One such type is NCP1060AD060R2G, which provides a switching frequency of 40 kHz – 400 kHz and adjustable output current.

Application Field of NCP1060AD060R2G

NCP1060AD060R2G, a highly efficient and cost-effective A/C converter, is typically used in applications such as high efficiency off-line power supplies, adapters, chargers, and DC/DC converter pre-regulators. It is designed to provide control and protection of AC mains with an output current of up to 6A. It is manufactured by a series of integrated topologies, such as demand current limit, area mode control, turn-off converter, and auxiliary winding over-load protection, which makes it suitable for most of the Off-line switching power supplies.

Features

NCP1060AD060R2G features power supply voltage range of up to 240V AC and a maximum total output power of 120W. It offers adjustable output voltage from 4V to 28V and a primary side control to reduce EMI noise and improve EMC performance. This A/C converter also incorporates an internal temperature feedback loop that helps protect against over-temperature by reducing the output load. Additionally, over-voltage and overload protection is included to prevent malfunction due to an internal short circuit.

Working Principle

The working principle of NCP1060AD060R2G A/C converter is based on the hard switching technique, where a high frequency switching device is used to perform voltage and current conversions between DC and AC sources. The device consists of two main parts, the primary-side and the secondary-side switches. When the converter is powered, a high-frequency alternating current is produced. The primary-side switch turns off during the time when the current goes in the opposite direction, while the secondary-side switch turns on and supplies current to the load.Once the switch is closed, the primary side switch then senses the current flowing through it and starts charging the internal capacitor. This charge powers the secondary-side switch and provides voltage/current conversion until the current reaches its preset limit. Finally, the converter shuts down when the AC current decreases at the primary-side switch.

Conclusion

NCP1060AD060R2G, a highly-efficient and cost-effective A/C converter, is used in the field of off-line switching power supplies. It features an adjustable output voltage, an intelligent temperature feedback loops, and a primary-side control, which helps reduce EMI noise and improve EMC performance. It works on a hard switching technique, where alternating current is used to perform voltage and current conversions between DC and AC sources. Thus, NCP1060AD060R2G is an ideal solution for a variety of power management applications.
