Model UC2845BN
Description PWM The STMicroelectronics pulse width modulator (PWM) controller supports isolated and non isolated AC-DC and DC-DC switching mode power supplies. They are based on the most commonly used topologies in single ended configurations (such as flyback, forward, or quasi resonant controllers) and dual ended configurations (asymmetric half bridge, used for switch mode power supplies (SMPS)). The PMW controller also integrates comprehensive protection to enhance robustness and reliability. ### PWM (Pulse Width Modulation) Controllers, STMicroelectronics
