Milpitas, California (MILPITAS, CA) - Linear Technology Corporation (Linear Technology CorporaTIon) Release version LTC3722-1 H level, the device is a phase modulated full bridge DC / DC controller with adaptive or manual zero voltage switching (ZVS). ZVS of the device and the adjustable synchronous rectifier control delay timer can optimize efficiency, while reducing the size of the transformer and electromagnetic interference, for up to several kW is isolated high power applications.
LTC3722-1 adaptive zero voltage technique is achieved by detecting bridge MOSFET and the input voltage, the converter to adapt to the load current, temperature, component tolerances, drive circuit delaying any changes in the input voltage or the fluctuation. Other features further comprises: a fixed frequency current mode control, adjustable current limit, leading edge blanking, soft start, short circuit protection and programmable slope compensation. A precise low dropout regulator provides 5V up to 15mA of current supply auxiliary circuit.
H grade version operates at up to 150 ° C junction temperature, and E and I grade versions can withstand the maximum junction temperature of 85 ° C. H-class products tested to ensure they can withstand at 150 ° C the maximum junction temperature, which makes it well suited for automotive and industrial applications, because these applications are subject to high ambient temperatures.
LTC3722-1 using SSOP-24 package. H-grade version of one thousand approved purchase price of $ 6.24 per tablet. For more information, please visit www.linear.com.cn/product/LTC3722.
