The LM3448 and TPS92070 phase-dimmable, ac/dc LED drivers suit a wide range of solid-state lighting apps. The LM3448 adaptive, constant-off time ac/dc constant current LED regulator integrates a 600V MOSFET and interfaces optimally with 2W to 8W dimmable LED lighting drivers. The TPS92070 flyback ac/dc constant current LED driver controller works best with 6W to 20W dimmable LED lighting drivers. Both devices feature thermal shutdown, VCC under-voltage lockout, cycle-by-cycle peak current limit, and LED open protection. The LM3448 is available in a 16-pin SOIC package while the TPS92070 comes in a 16-pin TSSOP. Prices are $1.10 and $0.75 each/1,000, respectively. TEXAS INSTRUMENTS INC., Dallas, TX. (800) 477-8924.
