over operating free-air temperature range (unless otherwise noted)(1)
MIN TYP MAX UNIT
VVIN VIN to GNDP –0.3 30 V VENA, VPG ENA, PG to GNDP –0.3 7 V VFBVEE-COM FBVEE to COM -0.3 7 V VBSW-COM BSW to COM -10 25.5 V VBSW-VEE BSW to VEE -0.7 32 V VBSW-VEE_tran BSW to VEE (0.24ns transient) -2.1 33.4 V VCOM-VEE COM to VEE -0.3 10 V VVDD-COM, VFBVDD-COM VDD, FBVDD to COM –0.3 25.5 V VVDD-VEE VDD to VEE –0.3 32 V POUT_VDD_MAX Total output power at TA=25°C 3 W TJ Operating junction temperature range –40 150 °C Tstg Storage temperature –65 150 °C (1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If used outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.
6.2 ESD Ratings VALUE UNIT
Human-body model (HBM), per AEC Q100-002(1) ±2000 V V(ESD) Electrostatic discharge Charged-device model (CDM), perAEC ±750 V Q100-011 Section 7.2 (1) AEC Q100-002 indicates that HBM stressing shall be in accordance with the ANSI/ESDA/JEDEC JS-001 specification.
6.3 Recommended Operating Conditions
over operating free-air temperature range (unless otherwise noted)
MIN TYP MAX UNIT
VVIN Primary-side input voltage to GNDP during continuous operation 5.5(1) 12 20 V VVIN Primary-side input voltage to GNDP during overvoltage transient 28 V VENA Enable to GNDP 0 5.5 V VPG Power-Good to GNDP 0 5.5 V VVDD-COM VDD to COM 15 18 20 V VVDD-VEE VDD to VEE 15 22 25 V VCOM-VEE COM to VEE 2 4 8 V TA Ambient temperature –40 125 °C TJ (2) Junction temperature –40 150 °C (1) See the VVIN_UVLO_R and VVIN_ UVLO_F electrical characteristics for the minimum operational VVIN. (2) See the Typical Characteristics section and COM_VEE Output Capability section for maximum rated load values across temperature and VVIN conditions for different (VDD-COM) and (COM-VEE) output voltage settings. 6 Submit Document Feedback Copyright © 2026 Texas Instruments Incorporated Product Folder Links: UCC34141-Q1 Document Outline 1 Features 2 Applications 3 Description Table of Contents 4 Device Comparison 5 Pin Configuration and Functions 6 Specifications 6.1 Absolute Maximum Ratings 6.2 ESD Ratings 6.3 Recommended Operating Conditions 6.4 Thermal Information 6.5 Insulation Specifications 6.6 Electrical Characteristics 6.7 Safety Limiting Values 6.8 Typical Characteristics 7 Detailed Description 7.1 Overview 7.2 Functional Block Diagram 7.3 Feature Description 7.3.1 Power Stage Operation 7.3.1.1 VDD-COM Voltage Regulation 7.3.1.2 COM-VEE Voltage Regulation 7.3.1.3 COM-VEE Output Capability 7.3.2 Output Voltage Soft Start 7.3.3 ENA and Power-Good 7.3.4 Protection Functions 7.3.4.1 Input Undervoltage Lockout 7.3.4.2 Input Overvoltage Lockout 7.3.4.3 Output Undervoltage Protection 7.3.4.4 Output Overvoltage Protection 7.3.4.5 Output Short Circuit Protection 7.3.4.6 Over-Temperature Protection 7.3.4.7 BSW Pin Faults Protection 7.4 Device Functional Modes 8 Application and Implementation 8.1 Application Information 8.2 Typical Application 8.2.1 Design Requirements 8.2.2 Detailed Design Procedure 8.2.2.1 VDD-COM Voltage Regulation 8.2.2.2 COM-VEE Voltage Regulation and Single Output Configuration 8.3 System Examples 8.4 Power Supply Recommendations 8.5 Layout 8.5.1 Layout Guidelines 8.5.2 Layout Example 9 Device and Documentation Support 9.1 Third-Party Products Disclaimer 9.2 Documentation Support 9.2.1 Related Documentation 9.3 Receiving Notification of Documentation Updates 9.4 Support Resources 9.5 Trademarks 9.6 Electrostatic Discharge Caution 9.7 Glossary 10 Revision History 11 Mechanical, Packaging, and Orderable Information
