Voltage Regulators - DC DC Switching Regulators datasheet and documents for UCC3941D-3
Voltage Regulators - DC DC Switching Regulators Overview
The UCC3941D-3 is a synchronous boost switching regulator IC from Texas Instruments, designed for low input voltage applications. It operates with an input voltage range of 1.1V to 3.2V and provides a fixed output voltage of 3.3V. The device delivers up to 60mA of output current in a single positive output configuration. It utilizes a boost topology and is housed in an 8-SOIC package (0.154" width). The component supports surface mount installation and functions within a junction temperature range of 0°C to 70°C.
Voltage Regulators - DC DC Switching Regulators Feature Summary
- Synchronous rectification architecture for improved efficiency
- Optimized for operation from single or dual alkaline cells
- Fixed 3.3V output capability
Voltage Regulators - DC DC Switching Regulators Applications
- Single cell battery powered devices
- Dual alkaline cell systems
- Low voltage boost conversion circuits
Voltage Regulators - DC DC Switching Regulators Procurement Notes
Verify the specific suffix 'D-3' against the manufacturer's official documentation to confirm the fixed 3.3V output variant. Ensure the 8-SOIC package dimensions match the design constraints. Confirm RoHS compliance status and moisture sensitivity level requirements for the assembly process before procurement.
Voltage Regulators - DC DC Switching Regulators Selection Notes
Select this component when a fixed 3.3V output is required from a low input source between 1.1V and 3.2V. The synchronous design offers better efficiency compared to non-synchronous alternatives at similar current levels. Consider the 8-SOIC package size for PCB layout constraints and verify thermal performance within the specified operating temperature range.
Voltage Regulators - DC DC Switching Regulators Part Context
The UCC3941 family consists of low input voltage single inductor boost converters. This series is specifically engineered to step up voltages from single or dual alkaline cells to standard logic levels like 3.3V or 5V. The UCC3941D-3 represents the fixed 3.3V output version within this family, sharing core features with adjustable variants like the UCC3941-ADJ.
Voltage Regulators - DC DC Switching Regulators Replacement Considerations
Public confirmed substitutes include UCC3941PWG4 and UCC3941DTR-3. Verify pinout compatibility and package type differences between SOIC and TSSOP variants if substituting.
