HBS SERIES - 150 WATT
DESCRIPTION
FEATURES
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 maxi-
mum 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
