Detailed Description for TPS54040DGQR
Product Overview
The Texas Instruments TPS54040DGQR is a positive, adjustable-output buck switching regulator for single-rail step-down conversion. It accepts input voltages from 3.5 V to 42 V and provides one output adjustable from 0.8 V to 39 V at up to 500 mA. The device operates over a junction temperature range of -40°C to 150°C and uses a surface-mount 10-PowerTFSOP, 10-MSOP (0.118", 3.00mm Width) package. Its switching frequency range is 100 kHz to 2.5 MHz, and it is a nonsynchronous buck regulator.
Key Features
- Positive single-output buck topology with adjustable output
- Input range: 3.5 V to 42 V
- Output adjustable from 0.8 V to 39 V at 500 mA
- Switching frequency range: 100 kHz to 2.5 MHz
- Nonsynchronous rectifier; 10-HVSSOP surface-mount package
Applications
- Single-rail step-down conversion to a lower positive output
- Adjustable positive voltage regulation on boards with 3.5 V to 42 V supplies
- Surface-mount power rail generation in embedded control hardware
Design & Procurement Notes
Design considerations focus on the 3.5 V to 42 V input range, the 0.8 V to 39 V adjustable output, and the 500 mA output current. The 100 kHz to 2.5 MHz switching frequency range supports trade-offs in converter design. The nonsynchronous rectifier status should be included in power-stage loss analysis. The 10-HVSSOP surface-mount package and -40°C to 150°C junction temperature range support surface-mount board layouts and thermal budgeting.
