The RGW3 and RGUW3 series of 3-W dc/dc converters are available in both 0.74 x 0.50 x 0.33-in. DIP and SMT packages and weigh 0.16 oz. The RGW3 series operates over 2:1 input voltage ranges from 4.5 to 9, 9 to 18, 18 to 36, or 36 to 75 Vdc. The RGUW3 operates over 4:1 input voltage ranges from 4.5 to 18, 9 to 36, or 18 to 75 Vdc. These two series have 3.3-, 5-, 9-, 12-, and 15-Vdc single-output models and ±5-, ±12-, and ±15-Vdc dual-output models.
Standard features for both dc/dc converter series include efficiency up to 83%, 1,600-Vdc I/O isolation (3,000 Vdc is optional), remote on/off, 100-kHz switching frequency, and continuous short circuit protection. They operate over an ambient temperature range of –40°C to +85°C without derating. (Ea/large qty: RGW3 single output, $12.50 ea; RGW3 dual output, $12.95; RGUW3 single output, $13.50; RGUW3, $14.20 — available now.)
