AnalogicTech offers a range of products ideally suited to meet the power management requirements of portable players on the market today. From ICs that charge the Li-ion battery to the USB On-the-Go interface device that allows you to download tunes from your WCDMA phone, AnalogicTech offers a wide choice of components. For the main power supply rail and to power the hard disk drive, a highly efficient range of DC/DC converters is available which can be combined with slew-rate controlled load switches or TrenchDMOS power MOSFET switches to conserve power. For the audio codec, LDO linear regulators are available with low self noise and high PSRR. Ultra-low quiescent current LDOs power the real-time clock and memory retention. Voltage regulated Step-Up charge pumps provide power for the LCD display. Finally for color display models, AnalogicTech offers a wide range of white and RGB LED drivers.
