375Vin DC/DC Mini Modules

375Vin DC/DC Mini Modules
Vicor has announced the addition of eight mid-power Mini DC-DC converters to the 375 Vdc input family: a 100 W model at 3.3 Vout; 150 W model at 5 Vout; and 200 W models at 12, 15, 24, 28, 36, and 48 Vout. These half-brick modules — which incorporate Vicor’s patented low-noise Zero-Current and Zero-Voltage Switching (ZCS/ZVS) —can be used in a variety of applications, including off-line systems with autoranging or PFC front ends, industrial and process control, distributed power, medical, ATE, communications, defence, and aerospace. Low-noise ZCS/ZVS greatly reduces the design effort and filtering costs required for power converters to meet agency conducted emissions requirements.

250mA Micropower LDOs can handle up to 80V Input

250mA Micropower LDOs can handle up to 80V Input
Linear Technology has announced the LT3012 and LT3013, micropower LDOs with input voltage capability up to 80V. The LT3012 and LT3013 feature low dropout voltage of only 400mV while delivering up to 250mA of load current. The wide adjustable VOUT capability from 1.24V to 60V makes them ideal for automotive, 48V telecom backup supplies and industrial control applications. Additionally, their very low quiescent current as low as 40uA (operating) and 1uA (shutdown) make them an excellent choice for battery-powered memory keep alive systems that require extended run times. The LT3013's Powergood flag feature is programmable and indicates output regulation.

Very Fast Low Distortion, Low Noise Differential Amplifiers/ADC Drivers Simplify System Design

Very Fast Low Distortion, Low Noise Differential Amplifiers/ADC Drivers Simplify System Design
Linear Technology has introduced the LT6402 and LT6411, two new differential amplifiers suitable as high-speed ADC drivers, twisted-pair line drivers and single-ended to differential signal converters. These new products utilize a novel design topology to integrate precision gain-setting resistors on-chip. In addition to simplifying system design and reducing external component count, these devices optimize distortion power and noise performance, critical for high-speed communications applications.
