TPS62615YFDR

Voltage Regulators - DC DC Switching Regulators Overview

The TPS62615YFDR is a fixed-output buck converter from Texas Instruments, delivering a regulated 1.2 V output at up to 350 mA. It operates within an input voltage range of 2.3 V to 5.5 V and utilizes a fixed 6 MHz switching frequency. The device features a low quiescent current of 31 uA and supports shutdown functionality. Packaged in a compact DSBGA-6 (YFD) footprint with a profile under 0.4 mm, it functions across an industrial temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a high-efficiency synchronous buck topology optimized for space-constrained designs.
• Utilizes a fixed 6 MHz switching frequency to minimize external passive component size.
• Includes a dedicated shutdown pin to significantly reduce standby power consumption.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable battery-powered consumer electronics
• Wireless communication modules
• Smartphones and handheld devices

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix YFDR corresponds to the DSBGA-6 package and 1.2 V fixed output variant. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure procurement channels provide valid traceability records for quality assurance purposes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.2 V rail is required with minimal board space constraints. The 6 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the 350 mA load requirement does not exceed the device's thermal limits within the target enclosure design.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TPS626xx series of high-efficiency step-down converters. It shares the same DSBGA-6 package and 6 MHz architecture as other variants in the family, such as the TPS62612 and TPS62674, which differ primarily in their fixed output voltages and maximum current ratings.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct functional substitutes include TPS62612YFDR (1.5 V output) and TPS62674YFDR (1.26 V output). These parts share identical pinouts and packaging but require verification of output voltage compatibility with the target circuit design.
