... The HV9961 demoboard is a high-brightness LED driver employing the patent-pending average-mode constant current control scheme by Supertex Inc. The power conversion stage of the HV9961DB1 consists of a diode bridge rectifier followed by a buck converter operating with fixed off-time of 20µs. The HV9961DB1 LED driver features tight regulation of the LED current within a few milliamps over the entire range of the input AC line and the output LED string voltage ...

... PWM Dimming The HV9961DB1 is capable of being PWM dimmed by ap- plying a square wave TTL compatible signal between PWMD and GND terminals. However, since there is no galvanic iso- lation on the board, care must be taken to prevent damage to the PWM dimming source and/or the HV9961DB1. One simple way is to isolate the LED driver from the AC line us- ing an isolation transformer ...
