Charge Pump Driver for LCD White LED Backlights

The ADM8845 uses charge pump technology to provide the power required to drive up to six LEDs. The LEDs are used for backlighting a color LCD display, having regulated constant current for uniform brightness intensity. The main display can have up to four LEDs, and the sub display can have one or two LEDs. The digital CTRL1 and CTRL2 input control pins control the shutdown operation and the brightness of the main and sub displays.

Variable Speed Control for Descaling Pumps in the

features attracted CSC to theACS 1000. The technology used by the ACS1000 means that it is suitable for direct fitting to existing and new medium voltage ACmotors.Direct retro-fit without matching the drive tothe motor is possible because the ACS 1000features a patented sine filter. This, byproducing a pure sine wave, avoids highvoltage spikes and common mode voltage,which can damage the motor insulationand bearings.The use of IGCT semiconductors contributesto the small footprint of the drive an

High Efficiency 1X/1.5X/2X Charge Pump for Six-Channel White LED Applications

The AAT3164 is a low noise, constant frequency charge pump DC/DC converter that uses a trimode load switch (1X), fractional (1.5X), and doubling (2X) conversion to maximize efficiency for white LED applications. The device is capable of driving up to six channels of LEDs at up to 30mA per channel from a 2.7V to 5.5V input. The current sinks may be operated individually or in parallel for driving higher-current LEDs. A low external parts count (two 1µF flying capacitors and two small 1µF capaci
