Linear's synchronous forward MOSFET driver eliminates signal transformer

April 2, 2014

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.

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

March 3, 2014

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.

Linear introduces 42 V, 4 A (IOUT), synchronous step-down silent switcher

October 21, 2013

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.

Linear introduces 100mA synchronous buck converter

May 13, 2013

Linear Technology announces the LTC3639, a 150V input-capable synchronous buck converter that delivers up to 100mA of continuous output current. It operates from an input voltage range of 4.5V to 150V, eliminating the need for an external transient suspension device. The LTC3639 utilizes internal synchronous rectification and a programmable peak current-mode design to optimize efficiency over a broad range of output currents.
