The UCC3809PW-2 is a PolyPhase® motor or lighting driver integrated circuit for use in flyback, forward or quasi-resonant AC-DC power converters. It offers integrated functions such as leading edge blanking, soft-start, line sensing, over current, over temperature, short circuit protection and capacitor discharge. All of these features combined make UCC3809PW-2 an ideal solution for offline switcher applications.
The UCC3809PW-2 is designed for use in motor control and lighting control applications with an input voltage range of 10V to 25V. It has a PWM frequency range of 28kHz to 320kHz and can drive a controlled output load of up to 600mA. It also includes an integrated current sense amplifier and a shutdown pin. The UCC3809PW-2 is available in both a 8- pin PDIP and 8-pin SOIC packages.
The UCC3809PW-2 works on the principle of pulse-width modulation (PWM) to control output voltage and current. It utilizes an operational transconductance amplifier (OTA) to generate the sawtooth waveform for the voltage control loop and an analog multiplier for the current loop. The UCC3809PW-2 has an internal current sense amplifier which produces an accurate current sense output to maintain over-current protection. An open drain output pin is provided so that the startup protection and leading edge blanking are activated whenever the output switches are OFF.
The UCC3809PW-2 has a wide range of features that help to make it an ideal choice for motor control and lighting applications. It supports auto-resonant control, allowing optimal noise performance. The occurrence of start-up current overshoot is reduced by using the internal soft start circuit which ramps the output current. There is also an adjustable over-current protection which prevents the converter from being damaged due to excessive loading. The device also includes an Over-Temperature protection circuit that triggers a shut down if necessary to protect the converter from damage. It also includes a high voltage capacitor discharge preventative circuit, which allows the user to shut down the converter without causing any damage.
In conclusion, the UCC3809PW-2 is an ideal choice for motor control and lighting applications. Its comprehensive feature set makes it a great solution for offline switcher applications. Its wide input voltage range, adjustable frequency range and robust protection circuit make it an ideal choice for an AC/DC power converter. The UCC3809PW-2 provides an integrated solution for motor control or lighting control, making it an ideal choice for a wide range of applications.
