UCC38085PWG4 belongs to the category of integrated circuits (ICs) specifically designed for power management applications.
This product is commonly used in various power supply systems, including switch-mode power supplies (SMPS), battery chargers, and LED drivers.
UCC38085PWG4 is available in a small-sized package known as PowerPAD™ SOIC-8. This package offers excellent thermal dissipation capabilities, enabling efficient heat transfer from the IC.
The essence of UCC38085PWG4 lies in its ability to regulate and control power supply systems efficiently, ensuring stable and reliable operation.
UCC38085PWG4 is typically sold in reels containing 2500 units per reel.
UCC38085PWG4 operates based on the principle of pulse width modulation (PWM). It generates a square wave signal with a variable duty cycle, which controls the power switch in the power supply system. By adjusting the duty cycle, the IC regulates the output voltage according to the feedback received from the load.
The error amplifier compares the feedback voltage with the reference voltage and adjusts the duty cycle accordingly. The current sense input monitors the output current, ensuring it remains within safe limits. The IC also incorporates protection mechanisms to safeguard against abnormal operating conditions.
UCC38085PWG4 finds applications in various power supply systems, including: - Switch-mode power supplies (SMPS) for computers, telecommunication equipment, and industrial machinery. - Battery chargers for portable devices, electric vehicles, and renewable energy systems. - LED drivers for lighting applications, such as streetlights, automotive lighting, and display backlighting.
