Recom Power introduces its popular R-78 series of switching regulators - a drop-in replacement for lossy linear types - now available with an extended input voltage range to 40 V and a wider operating ambient temperature to +100°C.

The new, cost-effective R-78CK-0.5 series is available with 3.3 V, 5 V, 12 V, or 15 V outputs, all rated at 0.5 A with conversion efficiencies up to 96%. Low losses achieved mean that heatsinking is not necessary, saving material and assembly labor costs while freeing up significant board space. Depending on variant, no, or minimal derating is required up to +100°C ambient with the parts operating at their minimum input voltages. At higher input voltages, the full 0.5 A output can be drawn up to a minimum of +65°C, depending on the variant.

Full input under-voltage, short-circuit, and thermal protection are provided, and the parts are certified to IEC/EN 62368-1 3rd edition.

Other improvements on the existing R-78E series include a lower allowable input-output differential voltage for the 3.3 V and 5 V output parts, lower quiescent current, and smaller package size in each dimension while still maintaining the standard pinout.
