UC2845BN is a high-current, high-speed PWM controller integrated circuit produced by STMicroelectronics. This device features a low start-up and operating current, synchronous rectification, and fast response times. It is engineered for use in switching power supplies, motor control, and lamp/LED dimming applications requiring high efficiency and low standby power consumption. The UC2845BN also includes two error amplifiers, one for voltage regulation and one for current regulation, and it includes protection circuits including an undervoltage lockout, an overload protector, and a soft-start circuit.
