The LTC3309B is a very small, high efficiency, low noise, monolithic synchronous 6A step-down DC/DC converter operating from a 2.25V to 5.5V input supply. Using constant frequency, peak current mode control at switching frequencies 3MHz-10MHz and minimum on-time as low as 22ns, this regulator achieves fast transient response with small external components. Silent Switcher architecture minimizes EMI emissions. The LTC3309B operates in forced continuous or pulse skip mode for low noise, or the low-ripple Burst Mode operation for high efficiency at light loads, ideal for battery-powered systems. The IC regulates output voltages as low as 500mV. Other features include output over-voltage protection, short-circuit protection, thermal shut-down, clock synchronization, and up to 100% duty cycle operation for low dropout. The device is available in a low profile 12-lead 2mm ? 2mm נ0.74mm LQFN package with exposed pad for low thermal resistance.APPLICATIONSOptical Networking, Servers, Telecom Automotive, Industrial, CommunicationsDistributed DC Power Systems (POL) FPGA, ASIC, ?P Core Supplies

The AD8337 is a low noise, single-ended, linear-in-dB, general-purpose variable gain amplifier (VGA) usable at frequencies from dc to 100 MHz; the ?3 dB bandwidth is 280 MHz. Excellent bandwidth uniformity across the entire gain range and low output-referred noise makes the AD8337 ideal for gain trim applications and for driving high speed analog-to-digital converters (ADCs).Excellent dc characteristics combined with high speed make the AD8337 particularly suited for industrial ultrasound, PET scanners, and video applications. Dual-supply operation enables gain control of negative-going pulses such as generated by photodiodes or photomultiplier tubes.The AD8337 uses the popular and versatile X-AMP? architecture, exclusively from Analog Devices, Inc., with a gain range of 24 dB. The gain control interface provides precise linear-in-dB scaling of 19.7 dB/V, referenced to VCOM.The AD8337 includes an uncommitted operational current-feedback preamplifier (PrA) that operates in inverting or noninverting configurations. Using external resistors, the device can be configured for gains of 6 dB or greater. The AD8337 is characterized by a noninverting PrA gain of 2? using two external 100 ? resistors. The attenuator has a range of 24 dB, and the output amplifier has a fixed gain of 8? (18.06 dB). The lowest nominal gain range is 0 dB to 24 dB and can be shifted up or down by adjusting the preamp gain. Multiple AD8337s can be connected in series for larger gain ranges, and for interstage filtering to suppress noise and distortion, and for nulling offset voltages.The operating temperature range is ?40?C to +85?C, and it is available in an 8-lead, 3 mm ? 3 mm LFCSP.Applications Gain trim PET scanners High performance AGC systems I/Q signal processing Video Industrial and medical ultrasound Radar receivers

Evaluation circuit EVAL-LT8357-AZ features the LT8357 as a 200kHz low EMI and low IQ, boost controller with a 24V output from 4.5V to 20V input. This evaluation circuit features Spread Spectrum Frequency Modulation (SSFM) and EMI filters to provide optimum EMI performance. The board also contains placeholders and an outline to attach clips for an optional EMI Shield attachment. This application circuit can output 2A (see Figure 4 Maximum Output Current vs VIN curve in the user guide). When placed in shutdown, the converter has very low quiescent current, ideal in automotive and other battery-powered applications. PULSE SKIP and BURST modes are selectable with jumper JP1. Each user-selectable option enables low quiescent current at light load and can also be combined with SSFM operation using JP1. The LT8357 boost controller IC operates over an input range of 3V to 60V, suitable for automotive, telecom and industrial applications. It exhibits a low quiescent current of 8μA, making it ideal for battery-operated systems. It drives a low side N-channel power MOSFET with a 5V split gate drive. The converter provides adjustable and synchronizable operation from 100kHz to 2MHz with SSFM option. At light load, either PULSE SKIP or low-ripple BURST mode can be selected to improve the efficiency. The LT8357 packs popular features such as soft-start, input undervoltage lockout, adjustable switching frequency and clock synchronization. The Power Good (PGOOD) flag indicates when the output voltage is in regulation. The LT8357 comes in a thermally enhanced 12-lead plastic MSE package. The LT8357 data sheet gives a complete description of the part, pins, features, operation, and application information. The data sheet must be read in conjunction with the user guide for EVAL-LT8357-AZ.
