• Systems utilizing common battery technologies with input voltages up to 6 V
• Applications demanding small solution size and high efficiency at moderate to high loads

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix RLTR corresponds to the VSON-7 package and reel packaging configuration. Confirm that the fixed 1.8 V output variant matches the system design requirements, as other output voltages exist within the TPS6208x family. Ensure compatibility with the required operating temperature range of -40°C to +85°C for the intended application environment.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.8 V output is required alongside a 3 A current capability. The 2.4 MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 268 uA quiescent current if standby power consumption is a critical constraint, noting that adjustable variants like the TLV62085 offer significantly lower quiescent currents.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TPS6208x series of high-frequency synchronous buck converters, which also includes the TPS62085 and TPS62086. These devices share similar topologies and control architectures but differ in output voltage configurations and quiescent current specifications. The TPS62087 specifically provides a fixed 1.8 V output, distinguishing it from adjustable or other fixed-voltage options in the same family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The TPS62085 and TPS62086 are pin-compatible members of the same series but feature different output voltage settings or quiescent current characteristics. Verify that the alternative part number meets the specific 1.8 V output requirement and thermal performance needs before substitution.
