Analog Devices Inc.
The LTC3524 is an integrated BIAS and white LED power converter solution for small/medium-sized polysilicon thin ?lm transistor (TFT) liquid crystal (LCD) display panels. The device operates from a single Lithium-Ion/polymer battery or any voltage source between 2.5V and 6V. A 1.5MHz synchronous boost converter generates a programmable low noise, high efficiency 25mA TFT supply of up to 6.0V. Regulated, low ripple charge pumps are used to generate up to +20V and ?20V at 2mA. Output sequencing is internally controlled to insure proper initialization and rapid discharge of the LCD panel in shutdown. A second 1.5MHz boost converter powers one or two LED strings with up to ?ve series elements each. LED current and display brightness can be controlled over a wide range using analog or digital means up to 25mA.The LTC3524 is offered in the 4mm ? 4mm 24-pin QFN package, minimizing the total solution footprint.Applications PDAs, Palmtop Computers Digital Still and Video Cameras Handheld GPS Portable Instrument Displays Portable Media Players
