TPS63050RMWR

Voltage Regulators - DC DC Switching Regulators Overview

The TPS63050RMWR is a synchronous step-up/step-down DC-DC converter from Texas Instruments, designed for single-cell lithium-ion or lithium-polymer battery applications. It operates within an input voltage range of 2.5V to 5.5V and provides an adjustable output voltage between 2.5V and 5.5V. The device delivers a maximum output current of 500mA with a switching frequency of 2.5MHz. Packaged in a compact 12-VQFN-HR (2.5x2.5mm) surface-mount housing, it supports operation across a temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix RMWR against official datasheets to confirm the tape-and-reel packaging configuration. Ensure compatibility with standard surface-mount assembly processes. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single-cell battery supply requires both buck and boost capabilities. The 2.5MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 500mA current limit and thermal performance within the small QFN package for final system integration.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TPS6305x family of tiny, single-inductor buck-boost converters. It shares architectural similarities with the TPS63051, which features a fixed 3.3V output, whereas the TPS63050 offers adjustable output voltage control via external resistors. Both variants utilize the same compact footprint and core control logic.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The TPS63051RMWT serves as a functional alternative if a fixed 3.3V output is acceptable, eliminating the need for feedback resistors. Verify pin-to-pin compatibility and ensure the fixed output voltage meets the target application requirements before substitution.
