Five-output regulator suits TFT-LCD panels

A five-output monolithic switching regulator, the LT3513 is packaged in a 5 x 7-mm QFN package. It offers a 2.2-A buck regulator, a 1.5-A boost regulator, a 250-mA boost regulator, a 250-mA inverter, and an LDO controller in one package. Each channel has an independent soft-start/run pin. The input voltage range of 4.5 to 30 V suits it for TFT-LCD applications, including automotive, industrial, and unregulated wall transformer-based systems.

The buck regulator delivers up to 1.2 A of output current for logic rails. A lower-voltage secondary-logic supply may be generated via the LDO controller and an external npn MOSFET. A step-up converter, a lower-power step-up converter, and an inverting converter provide the three independent output voltages required by LCD panels. (From $4.25 ea/1,000 — available now.)
