Triple-output LCD supply for monitors and notebooks
The TPS65150PWP is a triple-output power supply IC from Texas Instruments designed for LCD monitors and notebook displays. It integrates the bias rails needed for the gate-on voltage, gate-off voltage, and the source driver supply, reducing external component count versus a discrete solution. The IC operates from a 1.8 V to 6 V input rail, which means it can be powered directly from a 3.3 V or 5 V system bus without an intermediate regulator — a practical BOM simplification for space-constrained display assemblies. Its quiescent supply current is 1.9 mA, a figure that matters for notebook designs where every milliamp of standby draw extends battery life; the low Iq keeps the display power controller from eating into the platform sleep budget.
Layout engineers should allocate the pad area early; the exposed pad is not optional for thermal performance.
