PMIC (Power Management Integrated Circuit) is the key device for providing the power supply of the electronic products, UCC3809PW-2G4 power management integrated circuit is one of the most efficient PMIC devices. This device is suitable for the application in AC / DC Converters, Offline Switchers, etc. This article will focus on the application field and working principle of UCC3809PW-2G4.
UCC3809PW-2G4 offers an integrated solution for AC / DC converters in a single 8-pin SOIC. It integrates a high-accuracy voltage supervisor, an internal high-voltage AC switch, an adjustable high-frequency PWM controller, an adjustable overload protection, a power good flag, power-on reset circuit and an adjustable under-voltage lockout circuit. The integrated features with high efficiency, low standby current and fast transient response make the UCC3809PW-2G4 ideal for AC / DC converters.
The UCC3809PW-2G4 can provide up to 3.3A of continuous output current at a supply voltage of 11.5V up to 28V, and can accommodate peak to peak ripple in the supply ranges from 40 to 80V. The UCC3809PW-2G4 offers an adjustable output voltage range from 0.6 to 4.6V, and a one line rising time of less than 400µs. The PWM controller incorporates advanced adaptive dead time control for improved efficiency and reduced switching losses. The dead time can be programmed through the voltage feedback pin and output voltage selection pin.
UCC3809PW-2G4 can be used in off-line switchers, too. It integrates fixed frequency PWM controller, voltage supervisor, and current monitor block, which provide comprehensive protection features such as overload and short circuit Protections. It also contains adjustableenable function, reset flag and power good flag to enable the system to be controlled by an interrupt signal.
The working principle of UCC3809PW-2G4 can be divided into three stages, enabling stage, converting stage, and protection stage. During the enabling stage, an internal control signal will be generated to turn on the internal power switch provided a valid input voltage. Through the voltage feedback pin, the reference voltage will be generated so that the voltage loop can be closed for power tracking. During the converting stage, the PWM signal is generated to control the input source and output load according to the demand. During the protection stage, various protection circuits such as over-voltage, over-current and over-temperature will be activated to protect the system.
In a nutshell, UCC3809PW-2G4 is a highly integrated IC designed for AC/DC converters and off-line switchers. It can provide upto 3.3A of continuous output current and adjustable output voltage range from 0.6 to 4.6V. UCC3809PW-2G4 integrates several protection circuits which help to make the system performance reliable. The working principle of the IC consists of enabling stage, converting stage and protection stage.
