LCD bias PMIC — what the supply range and quiescent tell you
It accepts an 8.5 V to 14.7 V input rail — typically the main DC bus from an external adapter or a pre-regulated PSU — and generates the multiple regulated outputs needed to bias the panel's source drivers, gate drivers, and common electrode.
Why the 1.2 mA quiescent current matters in a display power design
At 1.2 mA supply current, the TPS65171RHAR keeps its own overhead low enough that standby power in a monitor stays under regulatory thresholds without a separate auxiliary converter.
Package and footprint — 40-VFQFN with exposed pad
Housed in a 40-VFQFN Exposed Pad package (supplier device package 40-VQFN, 6x6 mm), the TPS65171RHAR is a surface-mount QFN.
For a BOM that already specifies this device, the realistic path is independent-distribution sourcing — new-old-stock or surplus inventory that can be quoted against an RFQ. Expect to qualify the date code and marking consistency on any sourced units, since the part is no longer flowing through the authorized channel.
