... IN 0.41V Application Information General description The HV9967 employs Supertex’ proprietary control scheme achieving fast and very accurate control of average current in the buck inductor through sensing the switch current only. No compensation of the current control loop is required. The LED current response to PWMD input is similar to that of the peak-current control ICs, such as HV9910B ...

... MOSFET at the SW output, that could be used as a stand- alone switch for low-volt DC input applications source driver of an external depletion mode MOSFET (for example, DN2450 by Supertex). In both cases, the power for the IC is supplied from a linear 5.0V regulator that is also derived from the SW input. ...
