It switches from 20 kHz to 500 kHz and can operate at 100% duty cycle. The supply range is 3.6 V to 40 V, and the operating temperature range is -20°C to 85°C. ## Control features that matter for the design Dead-time control and frequency control are both accessible on this controller. Adjustable dead time lets you prevent cross-conduction in half-bridge or push-pull stages — a common gotcha in flyback converters where the transformer leakage inductance rings the switch node. Frequency control (via an external resistor or capacitor, per the datasheet) allows trading off inductor size against switching losses; at 500 kHz the magnetics shrink, but gate-drive losses rise. No clock-sync input means this part runs free-running — if you need synchronization to an external clock, the LM5150QURUMRQ1 offers that feature, though its duty cycle is capped at 87% and it targets automotive-grade applications. ## Lifecycle and sourcing posture The TL5001CDR carries an active lifecycle status and is ROHS3 compliant. If dual-sourcing is a priority, the UCC2806DWTR is a functional peer (boost/flyback/forward topology, dual outputs, 47 kHz typical) but note its 50% max duty cycle and 8 V minimum supply, which change the design constraints.","metaTitle":"TL5001CDR PWM Controller, Buck/Boost/Flyback, 20-500 kHz","metaDescription":"TL5001CDR PWM controller IC for buck, boost, and flyback topologies. 3.6-40 V supply, 20-500 kHz switching, 100% duty cycle, dead-time control.

The 100% duty cycle capability and adjustable dead-time control are directly relevant for flyback designs where transformer reset and switch-node ringing must be managed."},{"question":"What is the closest functional second-source for TL5001CDR?","answer":"The UCC2806DWTR is a functional peer (boost/flyback/forward, single-phase, transistor-driver output) but differs in key specs: 50% max duty cycle, 8 V minimum supply, and dual outputs.

Neither is a drop-in replacement — a design review is needed."},{"question":"How to set dead time on TL5001CDR?","answer":"Dead time is adjustable via an external resistor (typically connected to the DTC pin). The datasheet provides a characteristic curve relating resistance to dead time in nanoseconds. This allows tailoring the dead time to the power-stage switching speed and preventing shoot-through."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL5001CDR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL5001CDR when reusing this data.
