2 / 3 page rev. page date DESCRIPTION: dc-dc converter 2 of 3 09/2009 20050 SW 112th Ave. Tualatin, Oregon 97062 phone phone 503.612.2300 fax www.v-infinity.com fax 503.612.2383 PART NUMBER: VWRBS2 Recommended circuit It is best to test with full load and not to test without load. To further reduce output ripple, you may increase the external capacitor, choose a capacitor with low ESR, or add external inductor to the circuit as shown on the left. General: Cin: 5V, 12V 100μF 24V, 48V 10μF ~ 47μF Cout:100μF(typ) Lin: 4.7μH ~ 120 μH CS Pin By connecting a low ESR capacitor between this terminal and the pin-7 (Figure 1). the out- put ripple and noise may be further improved. Generally, the capacitance is no greater than 47uF. General Specifications Output short circuit protection Continuous Temperature rise at full load 15°C typ., 35°C max. Cooling Free air convection No-load power consumption 100mW (typical) Operating temperature range -40°C to +85°C Storage temperature range -50°C to +125°C Soldering temperature 300°C (1.5mm from case for 10sec.)
