Description
The HX1246-AGN is a wide input range step down DC/DC converter from a high voltage input
supply. HX1246-AGN achieves 2.7A continuous output current with excellent load and line regula-
tion. The synchronous architecture provides for highly efficient designs. Constant current and
constant voltage mode operation provide fast transient response and eases loop stabilization.
The HX1246-AGN features a dual-channeling CV/CC mode control functions. It operates in the
Constant output Current mode or Constant output Voltage mode. The over current protection
current value is set by current sensing resisters.
The HX1246-AGN requires a minimum number of readily available standard external compo-
nents. Other features include cable drop compensation, and thermal shutdown.
The HX1246-AGN converters are available in the industry standard SOP-8L packages.
