UCC38083DRG4 is an integrated PMIC - AC DC Converters, Offline Switchers that can be used for a variety of applications. It provides a low quiescent current, high efficiency, low EMI, and low standby power supply output. This device is suitable for consumer and consumer-oriented applications such as battery-operated applications, mains-connected adapters, and general purpose switch mode power supplies (SMPS) solutions.

The UCC38083DRG4 has two operational modes, continuous conduction mode (CCM) and discontinuous conduction mode (DCM). In CCM, the inductor current is always transitioning and thus provides a higher power factor, while in DCM the inductor current is constant thus allowing higher efficiency but lower output voltage and power factor. In either case, the UCC38083DRG4 works with a constant frequency current mode control, which allows for simpler operation and faster transient response.

The UCC38083DRG4 features advanced variable frequency control, allowing for operation at frequencies as low as 65kHz for reduced switching losses, and up to 500kHz for reduced filter size. This advanced frequency control also helps to reduce EMI by allowing for spread spectrum operation. In addition, it has an adjustable valley voltage that can help reduce EMI, reduce start-up time, and improves system reliability.

The UCC38083DRG4 also has built-in protection features, such as over-current protection, over-voltage protection, under-voltage protection, thermal shutdown, and power limiting. These features help to keep the system running reliably and effectively. The device also has a programmable frequency jitter and spread spectrum capability, allowing for further reductions in EMI and system noise.

The UCC38083DRG4 is an ideal solution for applications that require a high efficiency, low noise and low EMI power supply. It is capable of providing a wide range of output power from 50 watts to 500 watts, and is well suited for consumer-oriented applications. It can be used for a variety of AC/DC converters,Offline Switchers.
