Working Principles
The UCC3305DWTR is a voltage mode PWM controller IC used to regulate the output voltage in power supply applications. It operates by comparing the feedback voltage (FB) with a reference voltage (VREF) and adjusting the duty cycle of the output waveform accordingly. The error amplifier, compensation pin (COMP), and current sense input (CS) ensure precise voltage regulation. The soft start and shutdown control (SS/TR) provide a smooth startup and shutdown sequence. The synchronization input (SYNC) allows multiple controllers to operate in sync for multi-phase power supplies. The integrated high-side and low-side gate drivers (DRVH and DRVL) simplify the driving of MOSFETs. The bootstrap capacitor connection (BOOT) enables efficient driving of high-side MOSFETs.
