Description
HBS single output DC/DC converters provide up to 150 watts of output power in an industry standard, half-brick
package and footprint. The HBS Series features excellent efficiency, Class A conducted noise specifications, and fixed
switching frequency. The HBS features open-frame packaging, along with planar magnetics to provide maximum
useable power with minimal thermal constraints. The HBS Series is well suited for telecom, networking, and industrial
applications, and is fully compatible with production board-washing processes.
