Linear Technology Corp. announces the LT8612, a 6 A, 42 V input capable synchronous step-down switching regulator. Synchronous rectification delivers efficiency as high as 95% while Burst Mode® operation keeps quiescent current under 3 µA in no-load standby conditions. Its 3.4 to 42 V input voltage range makes it ideal for automotive and industrial applications. Its internal high efficiency switches deliver up to 6 A of continuous output current to voltages as low as 0.97 V.
Linear Technology Corp. announces the LT8710, its first synchronous SEPIC, inverting, boost and flyback multi-topology DC/DC controller. This synchronous device replaces the output diode with a high efficiency P-channel MOSFET, increasing efficiency, maximum output current (up to 10A) and eliminating the heat sink typically required in medium to high power applications, making the LT8710 highly versatile for a wide range of power supply designs.
Comtech Telecommunications Corp. announced that its Santa Clara, California-based subsidiary, Comtech Xicom Technology Inc., received an order for approximately $7 million from a U.S.-based system integrator for Traveling Wave Tube Amplifiers ("TWTAs") for a major U.S. Army satellite communications program.
TriQuint Semiconductor Inc., a leading RF solutions supplier and technology innovator, is releasing new phase shifters, high-power limiters and gallium nitride (GaN) MMIC amplifiers that can improve system performance, increase efficiency and reduce part counts in wide-ranging defense and commercial applications.
RFMD Inc., a global leader in the design and manufacture of high-performance radio frequency solutions, announced that the newest flagship Android smartphone incorporates its envelope tracking (ET) power amplifiers (PAs), antenna switch module, diversity switches and antenna tuner. This fifth generation smartphone from a leading Korea-based manufacturer is the slimmest and fastest Android phone to date and the first new smartphone to benefit from the improved power efficiency of RFMD's ET power amplifiers and antenna control solutions.
Skyworks Solutions Inc. introduces a step-down regulator with auto-bypass and low drop out that controls the operating voltage for multimode, multiband WDCMA or GSM/EDGE power amplifiers, delivering optimum efficiency for all operating states. Targeted for smartphones, mobile/cellular phones, wireless data cards and portable media devices, the SKY87000 integrates a bypass linear regulator that further improves system performance.
Richardson RFPD Inc. announces that it is taking advance orders and offering full design support capabilities for a new family of 48 V gallium nitride-on-silicon (GaN-on-Si) RF power transistors from Nitronex.
Cree Inc. announces that Shinry Technologies, a premier high-tech enterprise focused on energy efficient applications in transportation and lighting, employed Cree’s 1200V C2M family of SiC MOSFETs in its new, high-efficiency, hybrid electric and electric vehicle (HEV/EV) power converters to achieve industry-leading 96 percent efficiency. According to Shinry Technologies, Cree’s C2M SiC MOSFETS also enabled a 25 percent reduction in product size and reduced peak power losses by over 60 percent compared to the traditional silicon versions.
Linear Technology Corp. announces the LT8614, a 4 A, 42 V input capable synchronous step-down switching regulator. A unique Silent Switcher™ architecture reduces EMI/EMC emissions by more than 20 dB, well below the CISPR 25 Class 5 limit. Even with switching frequencies in excess of 2 MHz, synchronous rectification delivers efficiency as high as 96% while Burst Mode® operation keeps quiescent current under 2.5 µA in no-load standby conditions.
