It integrates a power sequencer, so you can program the power-up and power-down order of the four outputs without an external supervisor or CPLD. The two buck converters each deliver up to 3 A with an adjustable output from 0.7 V to 3.36 V, covering core and I/O rails for most application processors and FPGAs. The two LDOs provide 300 mA each, adjustable from 0.8 V to 3.3 V, suitable for analog or PLL supplies that need lower noise. Switching at 2 MHz keeps the inductor and capacitor values small, helping the board fit into a tight layout. A single PMIC replacing four discrete regulators plus a sequencer saves board area and simplifies the BOM. ## Package and rework — the wettable-flank advantage The 28-VFQFN with exposed pad is a common package, but the wettable-flank option makes a difference at the bench. Standard QFNs leave the side terminals hidden under the body after reflow, making solder-joint inspection a guessing game. With wettable flanks, the copper extends up the side of the package so you can see the fillet and verify the joint with a visual check or AOI. That matters when you're hand-reworking a board or qualifying a prototype run — you can see the connection is good without an X-ray. The 5x5 mm footprint keeps the thermal pad small enough that a hot-air station can lift the part without cooking the surrounding passives. ## Lifecycle status — still a current design-in choice The active status also supports long-term supply agreements through distribution.","metaTitle":"LP873345RHDT Dual Buck + Dual LDO PMIC, 2MHz, 28-VQFN","metaDescription":"TI LP873345RHDT dual high-current buck converter with two LDOs, sequencer, 2.5-5.5V supply, -40 to 125°C.
