2MHz, Five Output Regulator for TFT-LCD Panels

Linear Technology’s LT3513 is a five-output monolithic power source in a single package. It includes a 2.2A buck regulator, 1.5A boost regulator, 250mA boost regulator, 250mA inverter and an LDO controller. Each channel has an independent soft-start/run pin. The LT3513’s input range of 4.5V to 30V, making it ideal for a wide array of TFT-LCD applications, including automotive, industrial and unregulated wall transformer-based systems. Its 2MHz switching frequency keeps switching noise out of critical frequency bands, and ensures small external components. Combined with a 5mm x 7mm QFN package, the LT3513 provides a compact TFT-LCD power solution.
