2.25 MHz switching — small inductor, tight layout
The 2.25 MHz switching frequency lets the designer use a 1 µH to 2.2 µH inductor and small ceramic output capacitors, keeping the total solution footprint compact.

Product details
Frequently asked questions
Is TPS62424QDRCRQ1 RoHS compliant?
The TPS62424QDRCRQ1 is listed as RoHS compliant per its Texas Instruments product documentation. No RoHS exemption flags appear on the part marking or the datasheet.
Does TPS62424QDRCRQ1 require external compensation components?
The TPS62424QDRCRQ1 uses internal compensation — no external RC network is needed. The loop is stable with the recommended output capacitor values listed in the datasheet.
Can TPS62424QDRCRQ1 be used for 5V to 3.3V conversion?
The TPS62424QDRCRQ1 has fixed outputs of 1.1 V and 1.8 V. It cannot produce a 3.3 V output. For a 5 V to 3.3 V conversion, consider a single-output adjustable buck like the LMR33630APCQRNXRQ1.
