TPS62242DRVT

Voltage Regulators - DC DC Switching Regulators Overview

The TPS62242DRVT is a fixed-output synchronous step-down DC-DC converter manufactured by Texas Instruments. It operates within an input voltage range of 2 V to 6 V and provides a fixed output voltage of 1.2 V at a maximum load current of 300 mA. The device integrates a 2.25 MHz switching frequency, enabling the use of compact external components. It features a low quiescent current of 15 uA for efficient standby operation. The component is housed in a 6-WSON (2x2 mm) package with exposed pad and supports an operating temperature range from -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Synchronous buck topology ensures high conversion efficiency across the load range.
• Fixed 1.2 V output eliminates the need for external feedback resistors.
• High switching frequency allows for minimal passive component footprint.
• Low quiescent current supports extended battery life in portable applications.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable consumer electronics requiring stable 1.2 V logic supplies
• Battery-powered devices with single-cell lithium-ion or lithium-polymer inputs
• Embedded systems utilizing microcontrollers or digital signal processors

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix DRVT corresponds to the WSON-6 package and reel packaging configuration. Confirm RoHS compliance status through the official datasheet before integration. Ensure the fixed 1.2 V output aligns with target circuit requirements, as adjustable variants exist within the same family. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.2 V rail is required from a 2 V to 6 V source. The 300 mA current limit suits low-power digital loads. Consider the 2.25 MHz frequency for size constraints versus EMI sensitivity. Compare against adjustable models like TPS62240 if variable output voltages are needed later in the design phase.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TPS6224x series of ultra-small synchronous buck converters. It shares architectural similarities with the TPS62240 but differs in output configuration. While the TPS62240 offers adjustable output via an external resistor divider, the TPS62242 provides a fixed 1.2 V output, simplifying board layout and reducing component count for standard voltage rails.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

TPS62240DRVR serves as a functional alternative if adjustable output voltage is acceptable. Verify pin compatibility and thermal performance differences between the WSON-6 and SOT-23-THIN-5 packages when substituting. Ensure the replacement supports the required 300 mA load and 2.25 MHz switching frequency.
