TPS61040DBVR Low-Power Boost Converter

Specifications

Product Overview

The TPS61040DBVR is a Texas Instruments low-power boost converter for Power_Management designs requiring conversion from a 1.8 V to 6 V input range to an adjustable output voltage up to 28 V. The device operates with switching frequency up to 1 MHz and uses an internal switch with a 400 mA typical current limit for the TPS61040 variant.

The DBV package is a SOT-23 5-pin package with a 2.90 mm x 1.60 mm nominal body size. Recommended external component values include a 2.2 uH to 10 uH inductor, 4.7 uF input capacitor, and 1 uF output capacitor. Thermal data for the TPS61040 DBV 5-pin package includes 205.2 °C/W junction-to-ambient, 118.3 °C/W junction-to-case top, and 34.8 °C/W junction-to-board resistance.

Electrical limits include a 30 V maximum switch voltage, 600 mohm typical MOSFET on-resistance at VIN=2.4 V and ISW=200 mA, and 1.233 V typical internal reference. The EN pin supports shutdown by pulling EN to ground, reducing supply current to less than 1 uA.

Procurement Notes

When requesting a quote for TPS61040DBVR, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.

If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.

For power IC and power device sourcing, voltage rating, current rating, power dissipation, package thermal performance, protection features, qualification grade and application conditions should be reviewed before approval.
