LS7637 - REVERSE PHASE (TRAILING-EDGE) HALOGEN LAMP DIMMER

This page provides the datasheet information for the LS7637, a member of the LS7636 REVERSE PHASE (TRAILING-EDGE) HALOGEN LAMP DIMMER family.

Description

Since the operating currents of some electronic transformers are below the holding current of most triacs, a typical triac- OVC - Overcurrent Sense Input (Pin 6) based (leading-edge) dimmer may not operate properly when The voltage at this input is sampled every half-cycle in a driving an electroni

Features

  • Pushbutton or touch control of high-voltage lamps and all electronic transformer-coupled low-voltage halogen lamps.
  • Controls Fluorescents and CFLs via dimming ballasts.
  • Reverse-phase technology eliminates RFI generation.
  • “FO" versions power up Full On after.
