TL2843DRG4 Description

Short technical summary and product information.

The Texas Instruments TL2843DRG4 is an economy single-ended, current mode PWM controller. It is optimized for off-line and DC-to-DC converters, offering features necessary for fixed-frequency current-mode control schemes with minimal external components.

 

Key electrical specifications include a 500kHz switching frequency, a maximum duty cycle of 100%, and an undervoltage lockout (UVLO) of 8.4V/7.6V. The control mode is current, and it supports adjustable and fixed frequency operation, along with current limiting and an error amplifier. The device operates within a temperature range of -40°C to 85°C.

 

Available in PDIP (8-pin), SOIC (14-pin), and SOIC (8-pin) packages, the TL2843DRG4 is designed for surface mount and through-hole mounting types. Its features include low start-up current (<1mA), automatic feed-forward compensation, pulse-by-pulse current limiting, and high-current totem-pole output.
