TL2843D Description

Short technical summary and product information.

The Texas Instruments TL2843D is an obsolete economy single-ended, 500kHz current mode PWM controller designed for off-line and DC-to-DC converters. It offers features necessary for fixed-frequency current-mode control schemes with minimal external components.

 

Key electrical specifications include an operating voltage range of 7.6V to 30V and a maximum duty cycle of 97%. The controller operates at frequencies up to 500kHz and supports multiple topologies including Boost, Flyback, and Forward. It features a transistor driver output type and is not a synchronous rectifier.

 

Internal features include low start-up current (<1mA), undervoltage lockout with hysteresis, double-pulse suppression, a high-current totem-pole output, and an internally trimmed bandgap reference. The error amplifier has low output resistance. The device is designed to be interchangeable with UC2842 and UC3842 series controllers.

 

The TL2843D is available in a 14-SOIC package suitable for surface mounting. The operating temperature range is -40°C to 85°C (TA). Packaging options include large tape & reel (2,500 units) and tube (75 units).
