NCP1203D100R2

PMIC (Power ManagementIC) is an electronic device responsible for managing power distribution on a device. One type of PMIC is the AC/DC Converters, or offline switchers, which convert AC power to DC power, as well as regulate and/or switch the supply of power to multiple devices. The NCP1203D100R2 is a part of this family of products – specifically, a 100V highly integrated current-mode controller designed for Offline Switching Applications such as AC/DC adapters.

The NCP1203D100R2 has a variety of applications fields, the most popular of which is AC/DC adapter applications that operates directly from the AC line. This small, efficient package works well for making AC adapters with low standby power consumption, and high efficiency when transferring energy to the output.

The most basic information about the NCP1203D100R2 is its working principle. The 100V current-mode controller works by switching current at a rate determined by an externally injected voltage reference. The NCP1203D100R2 is implemented in current-mode control and employs a total-power-based Foldback Current-Limit technique, allowing the detection of short-circuit conditions up to 100V. This unit is also capable of soft-start and zero-current turn-off to prevent overshoot.

Furthermore, the NCP1203D100R2 includes advanced protection features. These features include auto-recovery protection circuitry to protect against short-circuit and over-temperature conditions, as well as a cycle-by-cycle current limit feature. This protection allows for a reliable operation of the system and helps to minimize risk in high-power applications.

The NCP1203D100R2 is capable of a wide range of performance levels and is suitable for a number of applications. Primarily, it is intended for offline flyback power converters, AC-DC adapters of up to 50W, and isolated dc/dc converters. Additionally, it is capable of achieving power levels up to 25W in flyback converters or 30W in boost converters.

In conclusion, the NCP1203D100R2 is a 100V current-mode controller that is designed for offline switching applications in AC/DC adaptors. It is a highly integrated device which offers multiple protection features and a wide range of performance levels for a variety of applications. With its range of abilities and many features, the NCP1203D100R2 is a practical and effective solution for designers looking for reliable and efficient AC/DC conversion.
