Product details

Buck converter for 400 mA rails — what the specs mean

Output is adjustable from 0.7 V up to the input voltage, so it covers common low-voltage rails like 1.2 V, 1.8 V, or 3.3 V.

Obsolete — planning the replacement path

The TPS62220DDCRG4 is officially marked obsolete. For new designs or long-term production, plan a migration to a current-generation synchronous buck from the TPS622 family or a pin-compatible alternative.

Housed in a SOT-23-5 Thin (TSOT-23-5) package, the part is surface-mount with a 0.95 mm pitch — straightforward for hand assembly or reflow.

Frequently asked questions

What is the replacement for TPS62220DDCRG4?

For a pin-compatible or functional replacement, evaluate current-generation synchronous buck converters from the TPS622 family or other manufacturers with similar input range, output current, and switching frequency.

Where can I buy TPS62220DDCRG4?

The TPS62220DDCRG4 is available through independent distribution.
