The R-78E series has around 30% lower losses than competing parts, for cooler running and high reliability, with a ‘pulse skipping’ mode maintaining high efficiency down to light loads. The parts also have much lower low conducted and radiated noise than other products on the market, requiring just a small LC input filter for compliance with EN 55032 Class A or B emissions limits. Overall size of the R-78E series parts is 11.6 x 8.5 x 10.4mm (L x W x H).
Protection features are comprehensive with cycle-by-cycle current limiting, short circuit, output over-voltage limiting, and automatic soft-start to reduce inrush current.
