Rochester Electronics UC1861J Environmental and export classification status description
The UC1861J is a high-performance, fixed-frequency, current-mode PWM controller specifically designed for off-line and DC-to-DC converter applications. It operates at a fixed frequency, adjustable from 40 kHz to 500 kHz, and provides a variety of features desirable for modern offline switching power supply systems. Functions: - Current-mode control for excellent line and load transient response - Internal soft-start function - Error amplifier with an output that can source or sink current - Precision voltage reference - Leading-edge blanking of the current sensing input - Pulse-by-pulse current limiting - Integrated output overvoltage protection Applications: - Off-line and isolated DC-DC converters - Uninterruptible power supplies (UPS) - LED lighting applications - Power factor correction (PFC) circuits - Telecom power supplies Alternative Components: 1. UC1861 2. UC1862 3. UC1863 4. TL494 5. SG3525 Embedded Modules: The UC1861J can be integrated into various power supply control modules and designs for applications requiring a robust and efficient power management solution. Related Q&A: 1. What is the difference between current-mode and voltage-mode control in PWM controllers like the UC1861J? 2. How does the soft-start function in the UC1861J controller help in reducing inrush currents during power-on? 3. Can the UC1861J be used in a flyback converter topology for isolated power supply designs? 4. What are the advantages of using current-mode control in switch-mode power supply designs with the UC1861J compared to voltage-mode control? 5. Are there specific design considerations when implementing the UC1861J in high-power applications such as server power supplies or industrial drives?
