Regulation is a pervasive feature of the telecommunications services industry today. Government-appointed regulators and judicial or quasi-judicial bodies oversee it in countries at all stages of economic development. Its primary purpose is to encourage, nourish and maintain competition in national and international telecommunications services markets. It is, therefore, a fundamental feature of the legal and commercial landscape within which network owners and service providers operate. The modern development of regulation may be traced to the liberalisation of the industry from national monopolies from the 1980s onwards.

Many telecommunications and computing applicationsneed high effi ciency step-down DC/DC converters thatcan operate from a very low input voltage. The highoutput power synchronous controller LT3740 is idealfor these applications, converting input supplies rangingfrom 2.2V to 22V to outputs as low as 0.8V with loadcurrents from 2A to 20A. Applications include distributedpower systems, point-of-load regulation and conversionof logic supplies.
