... IN sively complex and expensive in the offline AC or other high- voltage DC applications. The HV9961 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 HV9910B ...

... Fig.3. Typical linear dimming response of an HV9961 LED driver The linear dimming input could also be used for “mixed- mode” dimming to expand the dimming ratio. In such case a Supertex inc. pulse-width modulated signal of a measured amplitude be- low 1.5V should be applied at LD. Input Voltage Regulator The HV9961 can be powered directly from an 8 ...
