HV9912 Applications
* An internal 90V linear regulator powers the IC eliminating the need for a separate power supply for the IC. The IC also provides a FAULT output, which can be used to disconnect the LEDs in case of a fault condition using an external disconnect FET. HV9912 also provides a TTL compatible, low-frequen
