Richardson RFPD Inc. announced the availability and full design support capabilities for two GaN transistors from Qorvo. The 5W TGF3020-SM and 30 W TGF3021-SM input-matched transistors enable high linear gain and power efficiency in low-cost, space-saving surface-mount plastic QFN packages. The integrated input matching network enables wideband gain and power performance, and the output can be matched on-board to optimize power and efficiency for any region within the band.
Linear Technology Corp. announces the LTC3121, a 3 MHz current mode, synchronous boost DC/DC converter with integrated output disconnect. Its internal 1.5 A switches deliver output voltages as high as 15 V from an input voltage range of 1.8 V at start-up (0.5 V when running) to 5.5 V, making it ideal for battery or standard 3.3 V and 5 V power sources. The LTC3121 delivers up to 40 0mA of continuous output current at 1 2 V from a 5 V input.
Linear Technology Corp. introduces the LTC3877, a dual output multiphase synchronous step-down DC/DC controller with 6-bit voltage identification (VID) control that enables 10 mV output voltage step resolution, a necessary feature when powering FPGAs and ASICs with tight input voltage requirements. The LTC3877 operates over an input voltage range of 4.5 to 38 V and produces a fixed output voltage from 0.6 to 1.23 V when using VID and up to 5 V without VID.
Linear Technology Corp. announces the LTC3887-1, a dual output synchronous step-down DC/DC controller with I²C-based PMBus interface for digital power system management. The LTC3887-1 differs from the previously released LTC3887 by providing a three-state PWM signal, enabling the use of DrMOS, power blocks or similar power stages. The enhanced feature set includes a 70 ms power-up time and a fast ADC mode that provides an 8 ms update rate for one parameter.
