Product details

The TPS62046DRCRG4 is a synchronous step-down (buck) converter from Texas Instruments, delivering a fixed 3.3V output at up to 1.2A from a 2.5V to 6V input rail. The fixed 3.3V output simplifies the feedback network — no external resistor divider is needed.

Any replacement must be evaluated for pin-compatibility, output voltage, current rating, and switching frequency against the original design.

Package and thermal — 10-VSON with exposed pad

No tube or tray options are listed for this order code.

Frequently asked questions

What is a replacement for TPS62046DRCRG4?

No official replacement part number is listed by Texas Instruments. A functional replacement must match the fixed 3.3V output, 1.2A current rating, 1.25MHz switching frequency, and the 10-VSON (3x3) package footprint. Evaluate candidates from the TPS620 family or other TI buck converters with synchronous rectification and the same pinout.
