DC DC Switching Controllers datasheet and documents for TPS64203DBVTG4
DC DC Switching Controllers Overview
The TPS64203DBVTG4 is a non-synchronous step-down controller from Texas Instruments, designed for high-efficiency power conversion. It operates with an input voltage range of 1.8 V to 6.5 V and provides an adjustable output voltage between 1.2 V and 6.5 V. The device supports up to 3 A output current and features a low quiescent supply current of 20 uA. Operating within a temperature range of -40°C to +85°C, it utilizes a SOT-23-6 package.
DC DC Switching Controllers Feature Summary
- Non-synchronous buck controller topology optimized for efficiency
- Adjustable output voltage capability across a wide range
- Low quiescent current for enhanced battery life in portable systems
DC DC Switching Controllers Applications
- Systems powered from 5-V or 3.3-V buses
- Portable consumer electronics requiring efficient step-down regulation
- Battery-powered devices needing extended operational time
DC DC Switching Controllers Procurement Notes
Verify the complete part number including the G4 suffix to ensure compliance with RoHS standards and lead-free manufacturing requirements. Confirm that the SOT-23-6 package variant matches the design footprint. Cross-reference the datasheet revision to ensure compatibility with specific application notes regarding ceramic output capacitor selection and thermal performance expectations.
DC DC Switching Controllers Selection Notes
Select this component when an adjustable output voltage is required rather than a fixed rail. It is suitable for designs where the input source is a standard 3.3-V or 5-V bus. Consider the external inductor and switch requirements, as this is a controller rather than an integrated converter. Ensure the load current does not exceed the 3-A limit defined by the external switching element capabilities.
DC DC Switching Controllers Part Context
This part belongs to the TPS6420x family of step-down controllers. It shares functional similarities with the TPS64200 and TPS64201 but offers adjustable output flexibility. The DBVTG4 designation indicates the specific SOT-23-6 package and green (RoHS compliant) material composition provided by Texas Instruments.
DC DC Switching Controllers Replacement Considerations
The TPS64203DBVT is a compatible alternative within the same series. Both parts share identical electrical specifications and pinout configurations. Verify that the non-G4 version meets environmental compliance needs if RoHS is strictly required.
