Product details

Dual-rail power for automotive ECUs

The output voltages are programmable via external resistors, with fixed options of 1.575 V, 1.9 V, and 3.3 V available.

Switching frequency and inductor selection

The 2.3 MHz switching frequency lets you use a 1 µH to 2.2 µH inductor, keeping the total solution footprint under 30 mm². At this frequency the ripple current stays within 30 % of the DC output at full load, so the output capacitor can be a single 10 µF ceramic.

Automotive temperature grade and package

The exposed paddle is tied to the ground plane for both thermal and electrical return.

Frequently asked questions

What is the price of TPS62404QDRCRQ1?

Price is the primary decision factor for sourcing buyers when filling a BOM line.

Is TPS62404QDRCRQ1 in stock?

Availability directly determines whether the buyer can proceed with procurement or must look for alternatives.

What is the datasheet for TPS62404QDRCRQ1?

Design engineers need the datasheet to validate fit, pinout, and electrical characteristics before using the part.

Is TPS62404QDRCRQ1 obsolete or active?

Brokers and buyers need lifecycle status to avoid ordering a discontinued part that may become hard to source.

What is the replacement for TPS62404QDRCRQ1?

If the part is obsolete or unavailable, a drop-in replacement is critical to avoid redesign.

What is the lead time for TPS62404QDRCRQ1?

Lead time affects production scheduling and whether the part can meet the project timeline.
