Linear's synchronous forward MOSFET driver eliminates signal transformer

Linear Technology Corp. announces the LT8311, a high efficiency secondary-side MOSFET driver that operates without the need for primary control in an isolated synchronous forward converter. The LT8311’s unique preactive mode eliminates the need for a signal transformer for primary to secondary-side communication by sensing signals on the secondary side to control synchronous rectification. This mode reduces component count and solution size.

Two Microwave Detectors

Schottky Detectors BZD AtlanTecRF ePR

AtlanTecRF has two models of Zero Bias Schottky Detectors with high sensitivity and a wide operating temperature range. The first two frequency ranges offered are 10 MHz to 18 GHz and 2.0 to 8.0 GHz, both with sensitivity of 500 mV/mW and TSS of -50 dBm. Flatness over the 10 MHz to 18 GHz frequency band is +/-1.25 dB max and VSWR for each unit is 2.0:1.

Linear introduces flyback synchronous rectifier driver that provides 10 A output current

Linear Technology Corp. announces the LT8309, a flyback secondary-side synchronous rectifier driver that replaces the output diode with a MOSFET, allowing up to 10A output current without the use of a heat sink. The maximum output current of a flyback power supply has been limited by the power loss and heat generated from the output diode when no heat sink is used.

Step-Down Switching Regulator: LT8612

LT8612Linear 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's 80 V synchronous SEPIC/inverting/boost DC/DC controller delivers up to 10 A output current

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.

Linear introduces a current-mode synchronous step-down DC/DC controller

Linear Technology Corp. introduces the LTC3875, a dual output current-mode synchronous step-down DC/DC controller that enables the use of very low DC resistance (DCR) power inductors by using a novel DCR sensing architecture that enhances the signal-to-noise ratio of the current sense signal. Power inductor DCR, as low as 0.2 milliohms can be used without a sense resistor to maximize converter efficiency and increase power density. This new DCR sensing technique dramatically reduces the switching jitter normally associated with low DCR sensing applications.
