Onsemi UC3845BDG Environmental and export classification status description
The Onsemi UC3845BDG is a pulse width modulation (PWM) controller integrated circuit designed for controlling power converters. It is commonly used in switch-mode power supply applications. Functions: 1. PWM Control: The IC generates a fixed frequency pulse width modulated waveform with adjustable duty cycle. 2. Error Amplifier: Compares a voltage feedback signal with a reference voltage to regulate the output voltage. 3. Soft Start: Provides smooth start-up operation to prevent high current surges. 4. Overcurrent Protection: Monitors output current and shuts down the device if the current exceeds a certain threshold. Applications: 1. Switch-mode power supplies (SMPS) for various electronics. 2. DC-DC converters for voltage regulation. 3. Battery chargers. 4. Inverters for motor drives. 5. LED driver circuits. Alternative Components: 1. TI UC3845: Similar functionality to Onsemi UC3845BDG. 2. STMicroelectronics L6565: A pulse-width modulator for high-efficiency resonant converters. 3. Infineon ICE3BR4765J: A continuous-mode quasi-resonant controller for high power density. Embedded Modules: The UC3845BDG itself does not have embedded modules, but it can be integrated with other components in a power supply circuit to control power conversion processes efficiently.
