Product details

What this switching controller is and where it fits

The Texas Instruments UC2874QTR-2 is a switching controller — a PWM control IC for DC-DC converter designs, not a complete module. It is the control brain for topologies such as boost, flyback, and forward converters, where the external power stage (MOSFET, diode, magnetics) is sized to the load. The part is marked as RoHS non-compliant, meaning the solder balls or lead finish contain lead — a critical flag for any RoHS-mandated production line or lead-free reflow profile.

Flyback converter use — what the part supports

Yes, the UC2874QTR-2 can be used in a flyback converter. As a switching controller, it provides the PWM drive and control logic; the flyback topology is one of the standard applications for this class of controller. The external transformer, primary switch, and secondary rectification are chosen by the designer to meet the output voltage and current requirements.

Frequently asked questions

Is UC2874QTR-2 RoHS compliant?

No, the UC2874QTR-2 is marked as RoHS non-compliant. This means it contains lead or other restricted substances above the RoHS threshold. It is not suitable for RoHS-mandated production lines unless an exemption applies.

What is the UC2874QTR-2 replacement or equivalent?

No official replacement or direct equivalent is listed in the available records. The UCC2806DWTR and LM5150QURUMRQ1 are functionally different parts — different output counts, topologies, and temperature grades — and are not drop-in substitutes. Verify compatibility against your design requirements before substituting.
