Demonstration circuit 679 features the LT3463EDD in two circuits. One circuit is optimized for small size (9mA max output current) and the other for high performance (13mA max  output current). Both circuits are dual output ±20V voltage regulators with a 2.7V to 6V input voltage range. The positive regulator is a boost converter and the negative rail is an inverting charge pump.

Demonstration circuit 686, featuring the LTC3780 controller, is a high efficiency buck-boost DC/DC converter that can regulate its output from input voltages both above and below the output. The demo board delivers 12V@5A from an input range of 5V to 32V.

Demonstration circuit DC702 is a 2.25 MHz step-down converter, using the LTC3406B-2 adjustable output monolithic synchronous buck regulator. The DC702 has an input voltage range of 2.5V to 5.5V, and is capable of delivering up to 600 mA of output current at a minimum input voltage of 3V. the output voltage is set to 1.8V. The DC702 is made for noise sensitive applications, due to the LTC3406B-2 operating in pulse-skipping mode at low load currents.

The LT3024 is a dual, micropower, low noise, low dropout regulator. With an external 0.01?F bypass capacitor, output noise drops to 20?VRMS over a 10Hz to 100kHz bandwidth. Designed for use in battery-powered systems, the low 30?A quiescent current per output makes it an ideal choice. In shutdown, quiescent current drops to less than 0.1?A. Shutdown control is independent for each output, allowing for flexibility in power management. The device is capable of operating over an input voltage range of 1.8V to 20V. The device can supply 100mA of output current from Output 2 with a dropout voltage of 300mV. Output 1 can supply 500mA of output current with a dropout voltage of 300mV. Quiescent current is well controlled in dropout.The LT3024 regulator is stable with output capacitors as low as 1?F for the 100mA output and 3.3?F for the 500mA output. Small ceramic capacitors can be used without the series resistance required by other regulators.Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting and reverse current protection. The device is available as an adjustable device with a 1.22V reference voltage. The LT3024 regulator is available in the thermally enhanced 16-lead TSSOP and 12-lead, low profile (4mm x 3mm x 0.75mm) DFN packages.Applications Cellular Phones Pagers Battery-Powered Systems Frequency Synthesizers Wireless Modems

DC732A: Demo Board for the LTC2923 Power Supply Tracking Controller.

The LT5519 mixer is designed to meet the high linearity requirements of wireless and cable infrastructure transmission systems. A high speed, internally 50? matched, LO amplifier drives a double-balanced mixer core, allowing the use of a low power, single-ended LO source. An RF output transformer is integrated, thus eliminating the need for external matching components at the RF output, while reducing system cost, component count, board area and system-level variations. The IF port can be easily matched to a broad range of frequencies for use in many different applications.The LT5519 mixer delivers +17.1dBm typical input 3rd order intercept point at 1GHz with IF input signal levels of ?10dBm. The input 1dB compression point is typically +5.5dBm. The IC requires only a single 5V supply.Applications Wireless Infrastructure Cable Downlink Infrastructure Point-to-Point and Point-to-Multipoint Data Communications High Linearity Frequency Conversion

The LTC2921 and LTC2922 monitor up to five supplies and force them to track on power-up in multiple supply systems. Using external N-channel pass transistors, the supplies can be ramped up at an adjustable rate. Automatic remote sense switching allows the DC/DC converters to compensate for series voltage drops in the wiring. An incorrect level on one or more of the supplies triggers disconnect of all supplies. Tight 1% accuracy and glitch immunity on the low 0.5V monitoring level ensure no false error disconnects.The LTC2921 and LTC2922 each feature an adjustable electronic circuit breaker to protect the VCC supply against short circuits. Capacitance at the TIMER pin programs the delays in the monitoring sequence.The LTC2921 includes three remote sense switches in a 16-pin narrow SSOP package, while the LTC2922 includes five remote sense switches in a 20-pin TSSOP package. Both parts are available for VCC supply voltages of 5V, 3.3V, and 2.5V.Applications Desktop Computers Plug-In Cards Telecom Infrastructure Supply Sequencing Instruments

The LT6553 is a high-speed triple video amplifier with an internally fixed gain of 2. The individual amplifiers are optimized for performance with a double terminated 75? video load and feature a 2VP?P full signal bandwidth of 400MHz, making them ideal for driving very high-resolution video signals. Separate power supply pins for each amplifier boost channel separation to 75dB, allowing the LT6553 to excel in many high-speed applications.While the performance of the LT6553 is optimized for dual supply operation, it can also be used on a single supply as small as 4.5V. Using dual 5V supplies, each amplifier draws only 8mA. When disabled, the amplifiers draw less than 100?A and the output pins become high impedance. Furthermore, the amplifiers are capable of turning on in less than 50ns, making them ideal for multiplexing and portable applications.The LT6553 is manufactured on our proprietary low voltage complementary bipolar process and is available in the 16-lead SSOP package that fits in the same PCB area as an SO-8 package.Applications RGB Amplifiers Coaxial Cable Drivers LCD Projectors

The LT5537 is a wide dynamic range RF/IF detector, operational from below 10MHz to 1000MHz. The lower limit of the operating frequency range can be extended to near DC by the use of an external capacitor.
