DC1414B-B: Demo Board for the LTM4601AHV 12A, 28VIN DC/DC µModule Regulator with PLL, Output Tracking and Margining.

The LT6604-15 consists of two matched, fully differential amplifiers, each with a 4th order, 15MHz lowpass ?lter. The ?xed frequency lowpass ?lter approximates a Chebyshev response. By integrating a ?lter and a differential amplifier, distortion and noise are made exceptionally low. At unity gain, the measured in band signal-to-noise ratio is an impressive 76dB. At higher gains, the input referred noise decreases, allowing the part to process smaller input differential signals without significantly degrading the signal-to-noise ratio.Gain and phase are highly matched between the two channels. Gain for each channel is independently programmed using two external resistors. The LT6604-15 enables level shifting by providing an adjustable output common mode voltage, making it ideal for directly interfacing to ADCs.The LT6604-15 is fully specified for 3V operation. The differential design enables outstanding performance at a 2VP-P signal level for a single 3V supply.

Demonstration Circuit 1419 is a 1.5MHz current mode step-down switching regulator with programmable output current limit featuring the LT3663. The current limit accurately controls the system power dissipation and reduces the size of the power path components. The demo board operates with a 7.5V to 36V (60 transients) input voltage range. The output can be set to 3.3V or 5V using jumper J4, and the current limit can be set to 0.6V, 0.8V, 1V or 1.2V using jumpers J2 and J3.

The LTC6605-7 contains two independent, fully differential amplifiers configured as matched 2nd order lowpass filters. The f?3dB of the filters is adjustable in the range of 6.5MHz to 10MHz.The internal op amps are fully differential, feature very low noise and distortion, and are compatible with 16-bit dynamic range systems. The inputs can accept single ended or differential signals. An input pin is provided for each amplifier to set the common mode level of the differential outputs.Internal laser-trimmed resistors and capacitors determine a precise, very well matched (in gain and phase) 7MHz 2nd order filter response. A single optional external resistor per channel can tailor the frequency response for each amplifier.Three-state BIAS pins determine each amplifier?s power consumption, allowing a choice between shutdown, medium power or full power.The LTC6605-7 is available in a compact 6mm ? 3mm 22-pin leadless DFN package and operates over a ?40?C to 85?C temperature range.Applications WCDMA ADC Driver/Filter Antialiasing Filter Single-Ended to Differential Conversion DAC Smoothing Filter Zero-IF Direct Conversion Receivers

The LTC1474/LTC1475 series are high efficiency step-down converters with internal P-channel MOSFET power switches that draw only 10?A typical DC supply current at no load while maintaining output voltage. The LTC1474 uses logic-controlled shutdown while the LTC1475 features pushbutton on/off. The low supply current coupled with Burst Mode? operation enables the LTC1474/LTC1475 to maintain high efficiency over a wide range of loads. These features, along with their capability of 100% duty cycle for low dropout and wide input supply range, make the LTC1474/LTC1475 ideal for moderate current (up to 300mA) battery-powered applications. The peak switch current is user-programmable with an optional sense resistor (defaults to 325mA minimum if not used) providing a simple means for optimizing the design for lower current applications. The peak current control also provides short-circuit protection and excellent startup behavior. A low-battery detector that remains functional in shutdown is provided . The LTC1474/LTC1475 series availability in 8-lead MSOP and SO packages and need for few additional components provide for a minimum area solution.Applications Cellular Telephones and Wireless Modems 4mA to 20mA Current Loop Step-Down Converter Portable Instruments Battery-Operated Digital Devices Battery Chargers Inverting Converters Intrinsic Safety Applications
