3 / 3 page 52 www.recom-international.com January-2007 3rd angle projection 8 PIN SIP Package XX.X ± 0.5 mm XX.XX ± 0.25 mm Pin 3 (CTRL) This pin provides an Off function which puts the converter into a low power mode. When the pin is ‘high’ the converter is OFF and when the pin is high ‘Z’ the converter is ON. There is no allowed low state for this pin. Voltage to be applied via a limiting resistor with a recommended value of 1K for RSO-05xx; 3.3K for RSO-12xx; RSO-24xx and 10K for RSO-48xx. Pin 5 (NC) This pin is used internally and must have no external connection. Pin 8 (NC*) No external connection allowed.
