The UCC28704DBVR-1 from Texas Instruments is a highly integrated, 6-pin off-line flyback controller designed for high-efficiency AC to DC power supplies. It features primary-side regulation, eliminating the need for opto-couplers and secondary feedback components, which simplifies design and reduces cost.
This controller supports <30mW no-load input power and achieves ±5% output voltage and current regulation. It operates at a maximum switching frequency of 85 kHz and offers features like enhanced dynamic load response, constant current output under-voltage protection (CCUV) with auto-restart, and cable compensation. Fault protections include input low line, output over-voltage, over-current, and short-circuit.
The UCC28704DBVR-1 is housed in a SOT-23-6 package, suitable for surface mounting. Its design is optimized for applications such as adapters and chargers for phones and tablets, USB Type-C AC adapters, low power AC to DC SMPS, and industrial/medical SMPS.
Efficiency performance exceeds DoE Level VI and EU CoC V5 Tier-2 standards, with typical efficiencies reaching up to 88% at 230 VAC with synchronous rectification.
