ASD150QB 150 Wa t t , H i g h E ff ic i enc y, Quart er B ric k DC/DC Co n ve rte r series Industry Standard Quarter Brick Package High Power Density up to 90W/ Inch ³ High Typical Efficiency of 91% Low Output Noise Metal Baseplate Thermal Protection Input Under Voltage Protection Output Over Voltage Protection Current Limit/Short Circuit Protection Adjustable Output Voltage 90-110% of Vo Remote Sense DESCRIPTION: The ASD150QB dc/dc converter is offered in the industry standard “quarter brick” size (2.28in. x 1.45in. x 0.50in.) for circuit board mounting. It is designed for use in a 24/28 Vdc (18-36Vdc) or 48 Vdc (36-75Vdc) input applications where exceptionally high density DC power is required. The ASD150QB utilizes an insulated metal substrate and is therefore well suited for the most rigorous requirements of COTS and thermally challenging industrial applications.
