Vicor today announced the addition of new members to its growing PI37xx family of Cool-PowerZVS buck-boost regulators . The new PI3740Cool-Power regulator supports an operating voltage range of 8 to 60 VDC and a regulated output voltage of 10 to 50 VDC, delivering up to 140 watts of power and up to 8 amps of output current with up to 96% efficiency. The PI3740 not only integrates Vicor's proprietary high-frequency zero-voltage switching (ZVS) switching technology, but also provides the perfect integration of conversion efficiency, power density, and performance for demanding, automotive, industrial, test automation, LED lighting, and battery charging. Ideal for applications such as.
Similar to all members of the PI37xx family, the PI3740 meets its "creative" performance specifications throughout the operating voltage range, eliminating the need for special custom circuits. The wide operating voltage range reduces the number of regulators and power supply designs that must be designed, configured, manufactured, invented, and maintained. For example, the PI3740 converter can be used in a wide range of applications that require the use of several different alternative voltage regulators with narrow operating voltage ranges. For example, the PI3740 is designed to integrate power and can be operated or charged with 12V and 24V battery power. Moreover, all Vicor PI37xx buck-boost converters are capable of seamless transition between buck mode (input voltage greater than output voltage) and boost mode (input voltage less than output voltage), ideal for regulator input voltages above And applications below the output voltage change.
The PI3740 fully integrates its controllers, power switches and support circuitry in a high-density, high-efficiency 10mm x 14mm x 2.5mm system-in-package (SiP). In addition, other features of the PI3740 include high frequency (1MHz) operation, parallel options, constant voltage and constant current (eg for LED lighting applications) operating modes, overvoltage, overtemperature and overcurrent protection, -40o to 115oC temperature range , as well as integrated current sense amplifiers and integrated general purpose amplifiers.
The newest member of the growing PI37xxCool-PowerZVS buck-boost regulator family offers the perfect integration of operating voltage range, efficiency, density and thermal performance, supported by a range of online design, system analysis and simulation tools. Help users quickly and cost-effectively configure high-density, high-performance reliable power systems.
