TPS62293DRVT

Voltage Regulators - DC DC Switching Regulators Overview

The TPS62293DRVT is a fixed-output synchronous step-down DC-DC converter manufactured by Texas Instruments. It operates with an input voltage range of 2.3 V to 6 V and provides a fixed output of 1.8 V at up to 1 A load current. The device integrates a 2.25 MHz switching frequency, enabling the use of small external components within its compact WSON-6 package. Key electrical specifications include a typical quiescent current of 15 uA during operation and a maximum shutdown current of 268 uA. It functions reliably across an ambient temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a high-frequency 2.25 MHz switcher to minimize passive component size.
• Features synchronous rectification for optimized power conversion efficiency.
• Supports forced PWM mode to maintain stable operation under light load conditions.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable battery-powered consumer electronics
• Embedded systems requiring efficient voltage regulation
• Industrial control modules

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix DRVT corresponds to the required tape-and-reel packaging configuration before ordering. Confirm that the fixed 1.8 V output aligns with the target circuit design requirements. Ensure the WSON-6 footprint matches the PCB layout constraints. Validate thermal management capabilities for the intended operating environment.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.8 V rail is required from a single-cell lithium-ion or similar battery source. The fixed output eliminates the need for external feedback resistors, simplifying the bill of materials. Consider the 1 A current limit and 2.25 MHz frequency as primary constraints for inductor selection and transient response requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TPS6229x family of low-noise, high-efficiency synchronous buck converters. The family shares common architectural features but varies in output voltage options and package configurations. The TPS62293 specifically denotes the fixed 1.8 V variant, distinguishing it from adjustable versions like the TPS62290.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The TPS62293DRVR is a pin-compatible alternative available in a tube package instead of the reel format specified by the DRVT suffix. Verify that the change in packaging does not impact automated assembly processes.
