High Input Voltage DC/DC Controller from Linear Tech
Linear Technology has announced a new high reliability (MP) grade version of the LT3724, a 60V (65V(MAX)) low quiescent current (100uA) switching regulator DC/DC controller used in step-down, step-up, inverting and SEPIC topologies. The LT3724MP operates, and is 100% tested, over a junction temperature range of -55°C to 125°C, compared to the I grade version's -40°C to 125°C operating temperature range.
Single Inductor High Efficiency Synchronous Buck-Boost Controller from Linear Technology
Linear Technology Corporation has announced a high reliability grade version of the LTC3780, a very high efficiency synchronous buck-boost switching regulator DC/DC controller that operates from input voltages above, below or equal to the output voltage. High power buck-boost circuits typically rely on transformers or two DC/DC converters, one for step-up (boost) and the other for step-down (buck) conversion.
Flyback Controller Charges Any Size Capacitor
Linear Technology has announced the LT3751, a flyback controller designed to rapidly charge large capacitors to voltages as high as 1000V. The LT3751 drives an external N-Channel MOSFET and can charge a 1000uF capacitor to 500V in less than 1 second, making it ideal for applications such as professional photoflash systems, RF security, inventory control systems and specialized high voltage power supplies.
IMVP-6/6+/6.5 Single-Phase DC/DC Controller
Linear Technology introduces the LTC3816, a single-phase synchronous step-down DC/DC controller implementing the Intel® IMVP-6®, IMVP-6+®, and IMVP-6.5® protocols.
