Onsemi UC2845BDR2G Environmental and export classification status description
The OnsemiUC2845BDR2G is a Pulse Width Modulation (PWM) controller IC designed for use in switch-mode power supplies and converters. It is part of ON Semiconductor's family of integrated circuits and is widely used for regulating power in various electronic devices. Functions: - Provides control for regulating the output voltage of switch-mode power supplies. - Generates PWM signals to drive power MOSFETs and control the power delivered to the load. - Monitors the feedback voltage and adjusts duty cycle to maintain a stable output voltage. - Supports adjustable frequency operation for flexibility in different applications. Applications: - Switch-mode power supplies (SMPS) - DC-DC converters - Battery chargers - LED drivers - Variable-frequency inverters - Industrial and automotive power supplies Alternative Components: - Texas Instruments UC2845 - STMicroelectronics TL494 - Infineon TEA173x series - Maxim MAX809 Embedded Modules: - Overcurrent protection - Thermal shutdown - Soft start - Under Voltage Lockout (UVLO) - Voltage feedforward --- Related Q&A: 1. What is the operating voltage range of the OnsemiUC2845BDR2G IC? - The operating voltage range typically spans from 8V to 35V, making it suitable for a wide range of power supply applications. 2. How does the soft start feature in the UC2845BDR2G benefit power supply designs? - The soft start function prevents sudden spikes in output voltage and current during power-up, reducing stress on components and improving system reliability. 3. Can the UC2845BDR2G be used in both step-up and step-down converter topologies? - Yes, the UC2845BDR2G is versatile and can be employed in various converter configurations, including both buck (step-down) and boost (step-up) designs. 4. What is the typical switching frequency range supported by the UC2845BDR2G? - The IC enables adjustable frequencies in the range of tens of kilohertz to hundreds of kilohertz, allowing optimization for efficiency and component size. 5. How does the overcurrent protection feature work in the UC2845BDR2G? - The overcurrent protection function monitors the load current and can shut down the power supply when the current exceeds a preset threshold, safeguarding the system against damaging current spikes.
