Flyback controller charges any size capacitor
Linear Technology has announced the LT3751, a flyback controller designed to rapidly charge large capacitors to voltages as high as 1000V. The LT3751 drives an external N-Channel MOSFET and can charge a 1000uF capacitor to 500V in less than 1 second, making it ideal for applications such as professional photoflash
Battery back-up system manager saves space and power - offers battery backup charge
Linear Technology has introduced the LTC4110, an autonomous multi-chemistry, single chip, high efficiency flyback battery charge and discharge manager for server, memory backup, medical equipment, and high reliability system applications. The LTC4110 features four operating modes: battery backup, battery charge, "no-loss" battery calibration and shutdown. Combining all these in a

1.8/1.3GHz, Low Distortion, Dual ADC Drivers Deliver Guaranteed Matching & Low Noise
Linear Technology has announced the LTC6420-20 and LTC6421-20, the industry's first high-speed dual differential ADC drivers with guaranteed gain matching, and exceptional noise and distortion performance. With guaranteed matched gain of ±0.25dB and matched phase of ±0.1° (typ), the LTC6420-20 reduces errors in multichannel systems such as IQ demodulation or
High Speed Synchronous N-Channel MOSFET Driver Delivers 5A for High Efficiency Buck or Boost DC/DC Converters
Linear Technology has introduced the LTC4443/-1, a high speed synchronous MOSFET driver designed to drive upper and lower power N-Channel MOSFETs in synchronous rectified converter topologies. This driver, combined with power MOSFETs and one of Linear Technology's many DC/DC controllers, forms a complete high efficiency synchronous regulator that can be
16-Bit Quad IOUT Multiplying DAC Achieves ±1LSB INL and DNL
Linear Technology has introduced the LTC2755-16, a quad 16-bit current output digital-to-analog converter (DAC) with six software-programmable output ranges. The LTC2755-16 guarantees 16-bit linearity (±1LSB (max) INL and DNL) over the industrial temperature range without any adjustment. Each DAC output can be individually programmed through a parallel interface or can
16-bit, 105Msps Serial Output ADC Conserves FPGA I/O Pins
Linear Technology has announced a 16-bit, 105Msps ADC that establishes a simple, new benchmark for digital communication between high speed ADCs and FPGAs. The LTC2274's new high speed 2-wire serial interface greatly reduces the number of data input/output (I/O) lines required between a 16-bit ADC and the FPGA from 16
