UC3843BN CURRENT MODE PWM IC SMD SOP-8
The UC3843BN is a high-performance current mode PWM controller IC, designed for efficient power regulation in switch mode power supplies (SMPS), DC-DC converters, and solar inverters. With fast response time, fixed frequency operation, and optimized duty cycle control, it ensures high efficiency and stability in energy-critical applications.
The SMD SOP-8 package allows for compact and efficient PCB designs, offering better thermal performance and space-saving advantages. Its built-in undervoltage lockout (UVLO), short-circuit protection, and leading-edge blanking enhance the safety and reliability of power circuits, making it an ideal choice for solar inverters.
