TPS62293DRVR

Voltage Regulators - DC DC Switching Regulators Overview

The TPS62293DRVR is a fixed-output synchronous step-down DC/DC converter from Texas Instruments. It operates with an input voltage range of 2.3 V to 6 V and provides a fixed 1.8 V output at up to 1 A load current. The device integrates a 2.25 MHz switching frequency, enabling the use of small external components. It features a WSON-6 package for compact board space. Quiescent current is specified at 268 uA during operation and 15 uA in shutdown mode. The operational temperature range extends from -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated synchronous rectification for high efficiency across load ranges
• Fixed 1.8 V output eliminates external resistor divider requirements
• High switching frequency allows for minimal passive component footprint
• Shutdown mode reduces quiescent current to 15 uA for battery conservation

Voltage Regulators - DC DC Switching Regulators Applications

• Portable consumer electronics requiring efficient power conversion
• Battery-powered devices needing extended runtime through low standby current
• Embedded systems utilizing 3.7V lithium-ion or lithium-polymer batteries
• Industrial control modules operating within standard commercial temperature limits

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix DRVR corresponds to the WSON-6 package and tape-and-reel quantity when ordering. Confirm that the fixed 1.8 V output aligns with target circuit requirements, as adjustable variants exist within the same family. Ensure compatibility with PCB thermal design guidelines for the WSON-6 footprint to maintain optimal heat dissipation during peak load conditions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a stable 1.8 V rail is required without external programming resistors. Compare against adjustable models like the TPS62290 if variable output voltages are necessary. Consider the 1 A current limit for load demands; higher current applications may require alternative series members. Evaluate the 2.25 MHz frequency against EMI constraints compared to lower-frequency alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TPS6229x family of high-efficiency synchronous buck converters. It shares architectural similarities with the TPS62290 but differs in output configuration. The family targets portable applications where size and efficiency are critical. Other members include adjustable versions and automotive-grade variants with extended temperature ratings.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

TPS62290DRVR offers adjustable output instead of fixed 1.8 V. TPS62293DRVT provides the same electrical specifications but in a cut-tape package format. TPS62290TDRVRQ1 is an automotive-grade equivalent with extended temperature range.
