This product is typically packaged in reels, with 3000 units per reel.
UCC3808APWTR-1G4 has the following pin configuration:
UCC3808APWTR-1G4 operates based on the voltage mode control principle. It compares the feedback voltage (FB) with a precise reference voltage to regulate the output voltage. The error amplifier adjusts the duty cycle of the PWM signal generated by the internal oscillator, which controls the power delivered to the load. The soft-start function gradually increases the duty cycle during startup to prevent excessive inrush current. Overcurrent protection monitors the current sense input (CS) and shuts down the controller if the current exceeds a set threshold. Undervoltage lockout disables the controller when the input voltage falls below a specified level.
UCC3808APWTR-1G4 finds application in various power management systems, including but not limited to: - DC-DC converters - Switching power supplies - Battery chargers - LED drivers - Industrial automation equipment - Automotive electronics
