The TL3843DR-8 from Texas Instruments is a current mode PWM controller optimized for off-line and DC-to-DC converters. It features a voltage range of 7.6V to 30V and can operate at switching frequencies up to 500kHz. The controller supports multiple topologies including Boost, Flyback, and Forward configurations.
This device is housed in an 8-SOIC package, suitable for surface mount applications. Key features include pulse-by-pulse current limiting, undervoltage lockout with hysteresis, and a high-current totem-pole output. The TL3843DR-8 is designed for interchangeable use with UC2842 and UC3842 series controllers.
Its control features include frequency control, and it is not designed for synchronous rectification or clock synchronization. The operating temperature range is from 0°C to 70°C. This component is RoHS3 compliant and has an MSL rating of 1.
