High Efficiency, 150V 100mA Synchronous Step-Down Regulator Download White Paper 280Ko

The LTC®3639 is a high efficiency step-down DC/DC regulator with internal high side and synchronous power switches that draws only 12μA typical DC supply current while maintaining a regulated output voltage at no load. With its wide input range of 4V to 150V and programmable overvoltage lockout, the LTC3639 is a robust regulator suited for regulating from a wide variety of power sources.

This month, Cherry is giving away five of its Energy Harvesting Evaluation kits, worth over 266 Euros each, for EETimes Europe's readers to win. Cherry's energy harvesting technology benefit mostly applications where a complex wire assembly and/or batteries would be inappropriate.

The required RF-energy is created by the mechanical actuation of the switch and the data is transmitted wirelessly using RF-technology. The technology is very easy to install, fit and forget, with two standardised package versions for industrial applications: a rocker switch for actuation by hand and a snap-action switch for mechanical actuation.
