Product details

What this 500 mA, 3 MHz buck regulator does

The synchronous rectifier keeps efficiency up without an external Schottky diode. Output is fixed at 1.2 V — no resistor divider needed.

TI lists the TPS62304YZDR as obsolete. The 8-DSBGA footprint is the tightest constraint for any pin-compatible swap; a replacement must match the ball map and the 3 MHz switching characteristic to keep the same external inductor and capacitor values.

Housed in an 8-bump DSBGA, the TPS62304YZDR is a wafer-level chip-scale package — no moulded body, just solder balls on the die.

Frequently asked questions

What is the direct replacement for TPS62304YZDR?

No official direct replacement is recorded in the available documentation. Any substitute must match the 8-DSBGA footprint, the 500 mA output capability, the 3 MHz switching frequency, and the fixed 1.2 V output — a parametric search across TI's current portfolio is the next step.
