UCC28085PWRG4 belongs to the category of integrated circuits (ICs) specifically designed for power management applications.
This IC is commonly used in various power supply systems, including switch-mode power supplies (SMPS), battery chargers, and LED drivers.
UCC28085PWRG4 is available in a small-sized surface-mount package, known as TSSOP-20. This package ensures easy integration onto printed circuit boards (PCBs) and efficient heat dissipation.
The essence of UCC28085PWRG4 lies in its ability to regulate and control power flow efficiently, ensuring stable and reliable operation of power supply systems.
UCC28085PWRG4 is typically supplied in reels containing 2500 units per reel.
UCC28085PWRG4 operates based on the principle of pulse-width modulation (PWM). It regulates the output voltage by controlling the duty cycle of the switching waveform. By adjusting the duty cycle, the IC maintains a stable output voltage regardless of load variations. The feedback loop continuously monitors the output voltage and adjusts the duty cycle accordingly.
During startup, the soft-start function gradually increases the duty cycle, preventing excessive inrush currents that could damage the power supply system or connected devices. The IC also incorporates various protection mechanisms such as overvoltage protection, overcurrent protection, and thermal shutdown to ensure safe operation under abnormal conditions.
