The HV9801A LED driver dims LED lamp brightness to one of four preset levels through simple, rapid toggling of a standard light switch. Light levels progress up and down sequentially and if the switch is turned off for more than a second, the lamp returns to full brightness. The HV9801A works with all existing light switches and doesn’t require installation of a wall dimmer. Available in SOIC-8 and SOIC-16 packages (HV9801ALG-G and HV9801ANG-G, respectively), pricing is US$0.72 and $0.84 each/1,000, respectively. SUPERTEX INC., Sunnyvale, CA. (800) 222-9883.
