UC2823DWTRG4

DC DC Switching Controllers Overview

The UC2823DWTRG4 is a high-speed PWM controller manufactured by Texas Instruments, designed for DC-DC switching applications. It supports multiple topologies including boost, buck, flyback, and forward converters. The device operates within a supply voltage range of 8.4V to 30V and features a switching frequency between 340kHz and 460kHz. It provides a maximum duty cycle of 80% and includes control characteristics such as current limiting, enable, frequency control, slope compensation, and soft start. Packaged in a 16-SOIC surface-mount format, it functions as a transistor driver with positive output configuration.

DC DC Switching Controllers Procurement Notes

This component is discontinued at Digi-Key and no longer sold by that distributor. Verification of current availability through other authorized channels or original manufacturer sources is required before procurement planning. Users should confirm the active status of inventory with alternative suppliers to ensure supply chain continuity. Cross-referencing part numbers with official Texas Instruments documentation is recommended to validate compatibility and sourcing options.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring support for multiple DC-DC topologies such as boost, buck, flyback, and forward converters. Ensure the design accommodates the specified operating temperature range of -25°C to 85°C and the supply voltage requirements between 8.4V and 30V. The 16-SOIC package must be compatible with the target PCB layout. Verify that the switching frequency range of 340kHz to 460kHz aligns with system performance goals.

DC DC Switching Controllers Part Context

The UC2823DWTRG4 belongs to the UC2823 series of high-speed PWM controllers from Texas Instruments. It is functionally related to variants like the UC2823AN and UC2823DW, differing primarily in packaging and specific manufacturing revisions. As a member of the PMIC category, it serves as a core switching controller for power management integrated circuits, distinct from lower-dropout voltage controllers like the UC2849.

DC DC Switching Controllers Replacement Considerations

The UC2823DWTR is listed as a manufacturer-recommended substitute. Verify functional equivalence and pin compatibility before substitution.
