Product details

The Texas Instruments TPS62321YEDR is a synchronous step-down (buck) converter with a fixed 1.5 V output, rated for 500 mA continuous output current.

If this part is on your BOM, you are looking at a one-time buy from whatever inventory remains in distribution.

Package and handling — 8-DSBGA field note

This comes in an 8-bump DSBGA package. No lab, no bench — swapping this on site is not realistic without a hot-air station and a stencil. The tiny footprint means the PCB layout needs tight decoupling right at the bumps; the datasheet layout recommendation is not optional.

Frequently asked questions

What is the exact replacement for TPS62321YEDR?

Engineers and buyers need a drop-in or functionally equivalent part for new designs or repairs without redesigning.

Where can I buy TPS62321YEDR with stock?

Sourcing buyers need immediate stock availability for production or maintenance to avoid delays.

Is TPS62321YEDR still in production?

Lifecycle status directly impacts procurement decisions and long-term supply assurance.

What are the cross reference options for TPS62321YEDR?

Brokers and design engineers need known compatible parts to source alternatives or support second sourcing.

What is the output voltage of TPS62321YEDR?

Design engineers must confirm the fixed output voltage matches their circuit requirements.

How much does TPS62321YEDR cost in volume?

Volume pricing affects BOM cost projections and sourcing decisions for large production runs.
