Display bias supply for LCD monitors and notebooks
The Texas Instruments TPS65141RGER is a bias-supply IC designed specifically for LCD monitors and notebook displays.
Supply range and quiescent current — the BOM trade-offs
The 2.7 V minimum input allows the part to run deep into a Li-ion discharge curve, while the 5.8 V ceiling accommodates a tightly regulated 5 V rail without an external LDO. At 700 µA supply current, the quiescent draw is low enough that the bias supply can remain enabled during sleep modes in a notebook without materially affecting standby time.
