PMIC (power management IC) is an electronic control device that performs a wide range of functions related to power management. It provides an efficient way to control and protect power system design. One of the most important application fields for PMICs is AC/DC converters, offline switchers, and the NCP1244BD065R2G is a good example.

The NCP1244BD065R2G is a resonant mode offline switcher for AC-DC database systems. It is an integrated power solution that is optimized for highly compact, low-power, highly cost-effective offline switcher applications. This PMIC is designed to comply with all current safety regulations, making it an ideal solution for medical, industrial, and consumer applications.

To understand the working principle of the NCP1244BD065R2G, it is important to know how the usually offline switcher works. Theresonant mode power supply works with two inductors, two capacitors, one diode and a transformer connected in series. An energy transfer is achieved by high frequency switching, meaning that the cycle starts with one of the two inductors connected to the circuit and the other disconnected, then the inductor that was connected gets discharged while at the same time the disconnected inductor gets charged, and the cycle starts again by connecting the new inductor to the circuit, this process continues in a loop and the power output is achieved due to the oscilliator that controls the speed at which the inductors are switched.

The NCP1244BD065R2G takes the resonant mode offline switcher concept one step further, building upon the principle of a resonant mode power supply by adding features such as integrated short circuit, over voltage, and over current protection. The NCP1244BD065R2G also includes an integrated Current Mode PWM controller that provides accuracy and stability in output voltage regulation. Additional features of this IC include an integrated oscillator and PFC controller, integrated under voltage lockout logic, and a soft start circuit.

The NCP1244BD065R2G is designed to be used in applications such as battery-powered charging stations, medical instrumentation, industrial drives, and consumer electronics with wide line voltage inputs. This PMIC is also suitable for power supplies with an output power ranging from 12 to 25 watts, offering high power efficiency in a compact package. The NCP1244BD065R2G also has a strong focus on low EMI, and its built-in EMI filtering capacitors are optimized for minimum common mode noise on the power output.

In summary, the NCP1244BD065R2G is an integrated power solution optimized for low-power, highly cost-effective offline switcher applications. It is designed to comply with current safety regulations and offers features such as integrated short circuit, over voltage, and over current protection, Current Mode PWM Controller, an integrated oscillator and PFC controller, integrated under voltage lockout logic, and a soft start circuit.
