Linear's 9 to 72 V ideal diode bridge controller now specified for military & automotive applications

March 5, 2014

Linear Technology Corp. announces the automotive (H-grade) and high reliability military (MP-grade) versions of the LT4320, an ideal diode bridge controller for 9 to 72 V systems. The LT4320 replaces a full-wave diode bridge rectifier with a low loss N-channel MOSFET bridge to reduce the power and voltage losses by a factor of ten or more. Power supply size is reduced as the enhanced power efficiency eliminates bulky heat sinks.

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 small boost DC/DC converter with avalanche photodiode current monitor

November 27, 2013

The LT3905 from Linear Technology is a fixed frequency, current-mode step-up DC/DC converter designed to bias avalanche photodiodes (APD) in optical receivers. The LT3905 features high side APD current monitoring with over five decades of dynamic range and better than 2% relative accuracy over the 3µA to 3mA range. The maximum APD current is programmed with a single resistor and a fast current limiter with indicator protects the APD during overload conditions.

Linear introduces ideal diode bridge controller that minimizes power loss and heat

October 23, 2013

Linear Technology Corp. introduces the LT4321, an ideal diode bridge controller that replaces two diode bridge rectifiers with low-loss N-channel MOSFET bridges to increase the available power and reduce heat dissipation in a Power over Ethernet Powered Device (PoE PD). IEEE 802.3 PoE specifications require PDs to accept DC supply voltages of any polarity over their Ethernet inputs.
