The LTC6406 is a very low noise, low distortion, fully differential input/output amplifier optimized for 3V, single supply operation. The LTC6406 input common mode range is rail-to-rail, while the output common mode voltage is independently adjustable by applying a voltage on the VOCM pin. This makes the LTC6406 ideal for level shifting signals with a wide common mode range for driving 12-bit to 16-bit single supply, differential input ADCs. A 3GHz gain-bandwidth product results in 70dB linearity for 50MHz input signals. The LTC6406 is unity gain stable and the closed-loop bandwidth extends from DC to 800MHz. The output voltage swing extends from near-ground to 2V, to be compatible with a wide range of ADC converter input requirements. The LTC6406 draws only 18mA, and has a hardware shutdown feature which reduces current consumption to 300?A. The LTC6406 is available in a compact 3mm x 3mm 16-pin leadless QFN package as well as an 8-lead MSOP package, and operates over a ?40?C to 85?C temperature range.

The LT3510 is a dual current mode PWM step-down DC/DC converter with two internal 2.5A switches. Independent input voltage, feedback, soft-start and power good pins for each channel simplify complex power supply tracking/sequencing requirements.Both converters are synchronized to either a common external clock input or a resistor programmable ?xed 250kHz to 1.5MHz internal oscillator. At all frequencies, a 180? phase relationship between channels is maintained, reducing voltage ripple and component size. Programmable frequency allows for optimization between efficiency and external component size.Minimum input-to-output voltage ratios are improved by allowing the switch to stay on through multiple clock cycles, only switching off when the boost capacitor needs recharging, resulting in ~95% maximum duty cycle.Each output can be independently disabled using its own soft-start pin, or by using the SHDN pin the entire part can be placed in a low quiescent current shutdown mode.The LT3510 is available in a 20-lead TSSOP package with exposed leadframe for low thermal resistance.Applications DSP Power Supplies Disc Drives DSL/Cable Modems Wall Transformer Regulation Distributed Power Regulation PCI Cards

Demonstration circuit 1187 is an RGB LED Driver and Charge Pump featuring the LTC3212. The LTC3212 is a low noise boost charge pump capable of driving three LEDs at up to 25mA each. The charge pump operates in either 1x or 2x mode, with automatic mode switching. Individual current sources allow each LED to be turned on individually, in combination with the other LEDs, or in white mode using a single wire interface. The demo board input voltage range is 2.7V to 5.5V. White mode optimizes the red, green, and blue current settings to provide the best white color. LED currents are regulated using internal low dropout current sources. Automatic mode switching optimizes efficiency by switching modes only when a dropout is detected.

The LT3595 is a high performance LED Driver designed to drive sixteen independent channels of up to 10 LEDs at currents up to 50mA. Series connection of the LEDs provides identical LED currents resulting in uniform brightness. Power switches, Schottky diodes, and compensation components are all internal, providing a small converter footprint and lower component cost. The high 2MHz switching frequency permits the use of tiny, low pro? le inductors and capacitors. A fixed frequency, current mode architecture results in stable operation over a wide range of supply and output voltage. A single external resistor sets the LED current for all sixteen channels, and dimming is then controlled for each channel by pulse width modulating the individual PWM pins. Relative current matching among the sixteen drivers is 8% and the PWM dimming range is 5000:1. The part is available in a 5mm x 9mm x 0.75mm 56-pin QFN package.
