# UCC28950TPWRQ1 Engineering Specifications **General Description** The UCC28950TPWRQ1 is an automotive-qualified phase-shifted full-bridge controller manufactured by Texas Instruments. It is specifically designed for high-efficiency isolated DC-to-DC power conversion systems requiring advanced control, high power density, and reliable operation in demanding automotive and industrial environments. The device implements phase-shifted pulse-width modulation control with programmable dead-time management to achieve zero-voltage switching across a wide load range. This soft-switching architecture significantly reduces switching losses, improves overall efficiency, minimizes electromagnetic interference, and enables higher switching-frequency operation. The controller integrates comprehensive protection and monitoring functions, including current limiting, overvoltage protection, soft-start control, and fault management. Its flexible architecture supports a wide variety of isolated power-supply topologies used in electric vehicles, onboard charging systems, telecommunications infrastructure, industrial power supplies, and high-performance DC-DC converters. Qualified to automotive reliability standards, the device is suitable for mission-critical applications requiring long-term operational stability and robust power-conversion performance. **Engineering Specifications** **Manufacturer:** Texas Instruments **Manufacturer Part Number:** UCC28950TPWRQ1 **Component Type:** Phase-shifted full-bridge PWM controller **Technology:** Advanced mixed-signal power-management integrated circuit **Control Method:** Phase-shifted pulse-width modulation **Converter Topology:** Full-bridge isolated DC-to-DC converter control **Switching Technique:** Zero-voltage switching support **Efficiency Enhancement:** Reduced switching losses through soft-switching operation **Dead-Time Control:** Programmable adaptive dead-time management **Gate Drive Outputs:** High-current complementary PWM outputs **Current Control:** Cycle-by-cycle current limiting capability **Soft-Start Function:** Programmable startup control **Synchronization Capability:** External synchronization support **Frequency Control:** Programmable switching frequency operation **Feedback Architecture:** Closed-loop voltage regulation support **Fault Management:** Integrated fault detection and shutdown capability **Protection Features:** Overcurrent protection, overvoltage protection, undervoltage lockout, fault shutdown, and soft-start protection **Automotive Qualification:** AEC-Q100 qualified **Reliability Grade:** Automotive-grade performance and reliability **Electromagnetic Compatibility:** Optimized for low-noise power-conversion applications **Power Supply Configuration:** Single-controller power-management operation **Temperature Stability:** Designed for extended automotive operating conditions **Control Flexibility:** Supports a wide range of isolated converter designs **System Integration:** Compatible with high-power MOSFET and IGBT switching stages **Operating Temperature Range:** Automotive temperature range **Package Type:** Thin Shrink Small Outline Package **Package Configuration:** Surface-mount package **Mounting Style:** Surface mount technology **Environmental Compliance:** RoHS compliant and lead-free **Quality Standard:** Automotive production and qualification standards **Typical Applications** Automotive DC-to-DC converters Electric vehicle power systems Battery management systems Onboard charging equipment Telecommunications power supplies Industrial power converters High-power isolated DC-DC modules Server and networking power systems Renewable energy conversion systems Automotive auxiliary power units Motor control power supplies Power-distribution architectures High-efficiency switching power supplies Advanced automotive electronics Mission-critical power-management systems #UCC28950TPWRQ1 #UCC28950 #TexasInstruments #PhaseShiftedFullBridge #PWMController #PowerManagement #DCDCConverter #AutomotiveElectronics #PowerSupplyDesign #ZeroVoltageSwitching #SoftSwitching #ElectricVehicle #IndustrialPower #PowerElectronics #ElectronicComponents #EngineeringSpecifications
