AnalogicTech offers power switching solutions to save power in digital photo frames using a battery or high voltage step down converters and an AC adapter. High-efficiency Step-Up and Step-Down voltage converters using inductive and/or capacitive techniques give the design engineer multiple options depending upon performance and size requirements.  Backlighting in the LCD panel of a digital photo frame uses white LEDs driven by regulators and LED drivers.  For the variety of LED arrays, a comprehensive range of smart switches – complete with short-circuit and thermal protection – provide protection to external ports for memory cards and USB. Dedicated solutions for battery charging, USB On-the-Go, and memory card switching and protection are also available. Additional solutions include ultra-low quiescent current LDO linear regulators, voltage monitors, and microprocessor supervisory circuits complete with watchdog timer.
