Overview

LSI/CSI UL ® LS7231-7234 (631) 271-0400 FAX (631) 271-0405 December 2000 LSI Computer Systems, Inc.
1235 Walt Whitman Road, Melville, NY 11747 A3800 TOUCH CONTROL LAMP DIMMER FEATURES: • Phase-lock loop synchronization allows use in Wall Switch applications.
• Provides brightness control of incandescent lamps with touch plates or mechanical switches.
• Controls the "duty cycle" from 23% to 88% (conduction angles for AC half-cycles between 41˚ and 158˚, respectively.
) • Operates at 50Hz/60Hz line frequency.
• Extension input for remote activation.
• Input for slow dimming.
• +12V to +18V DC Power Supply voltage.
(VSS - VDD) • LS7231 to LS7234 (DIP) - See Figure 1 LS7231-S to LS7234-S (SOIC) DESCRIPTION: LS7231 through LS7234 are a series of monolithic, MOS integrated circuits designed for the control of brightness of incandescent lamps.
The outputs of these ICs control the brightness of a lamp by controlling the firing angle of a triac connected in series with the lamp.
