Vicor's latest addition to its PI37xx family of cool-power ZVS buck-boost regulators, the PI3740, features an input operating voltage range of 8-60VDC and a regulated output voltage range of 10-50VDC.

Delivering up to 140W of power and up to 8A of output current at up to 96% efficiency, the PI3740 meets its performance specifications “out of the box” across the full breadth of its operating voltage ranges without the need for special circuit customisations, according to Vicor.

Wide operating voltage ranges reduce both the number of regulators and the number of power supply designs that must be designed, configured, manufactured, inventoried and maintained. The PI3740 converter, for example, can be used in a range of applications that would otherwise require the use of several alternative regulators having narrower operating voltage ranges, according to the company. For example, a power supply incorporating a PI3740 can be designed to operate from, or charge, both a 12V and a 24V battery source.

The PI3740 fully integrates its controller, power switches and support circuitry within a high density, thermally adept, 10mm x 14mm x 2.5mm SiP (System-in-Package). Other PI3740 features include: high frequency (1MHz) operation; parallel options; constant-voltage and constant-current (e.g for LED lighting applications) operating modes; over-voltage, over-temperature and over-current protection; -40°C to 115°C temperature range; and an integrated current sense amplifier and integrated general purpose amplifier.
