Innovative isolated and non-isolated SMT DC/DC converters
Over many years, high-efficiency switching converter replacements for the traditional ‘78xx series’ linear regulators have been released. Although ‘drop-in’ through-hole equivalent parts have been popular, surface-mount types are now preferred.
As one of the first manufacturers to make a switching regulator module, RECOM first addressed the market with an encapsulated ‘gull-wing’ 1A-rated part, the R-78AA-1.0 series, which has a wide input range of up to 18V, allowing 5V, 9V, 12V or 15V unregulated supplies to be used, and fixed regulated outputs of 1.5V,1.8V, 2.5V or 3.3V, in a volume of just 1.75cm3. For applications where a low-profile open-frame product was preferred, the RECOM ROF-78E series offered 0.5A rating with a wider input range of up to 36V and fixed output voltages of 3.3V, 5V or 12V in a total volume of 0.68cm3.
