DIMMABLE BALLAST CONTROL INTEGRATED CIRCUIT |
摘要 |
<p>An IC for controlling a power supply circuit for delivering power to a fluorescent lamp in accordance with an embodiment of the present invention includes a ballast control section operable to provide drive signals to the power supply circuit and an amplifier section integrated into the IC and operable to provide a dimming signal to the ballast control section. The ballast control section drives the power supply circuit to provide for dimming of the lamp based on the dimming signal. An IC for controlling a power supply circuit for delivering power to a fluorescent lamp in accordance with another embodiment of the present application includes a ballast control section operable to provide drive signals to the power supply circuit; and an amplifier section integrated into the IC. The ballast control section provides the drive signals to the power supply circuit, receives current sense signals indicative of current in said lamp, and responds to the current sense signals by modifying the drive signals.</p> |
