Portable electronic devices and LED lamps driving power IC market

Space and power consumption are most important aspects of portable electronics design. The engineers who use highly integrated small-size latest SoC chips prefer to use even smaller power supply modules and DC/DC converter ICs with highest power efficiency to power complex SOC chips. The need for high power-density and high-efficiency power converter occupying less space forcing power supply design engineers to think about new switching topologies and switching control. Sal Sestito, VP Business Development from iWatt (Dialog semiconductor has agreed to acquire iWatt) shared to this writer how his company is exploring the emerging opportunities in this market. iWatt, specialised in converter ICs for AC/DC adapter market seeing India as an important market for the simple reason of growing consumption of electronics in wide range of applications. Technology strengths of iWatt: iWatt has pioneered a voltage regulation method, where the voltage regulation is made on primary side of a power supply which results in reduction of cost and size. iWatt has 130 patents related to digital power control technology. iWatt's products play a role in both pluggable AC/DC adapters as well as LED lamps which powered by mains power supply. iWatt has integrated thermal derating feature in their LED driver ICs. iWatt collects the broad specification from its customers like PCB size, voltage and...
