TowerJazz and DMB Technology announced volume production and shipping of DMBT’s AC direct LED driver IC using TowerJazz’s 700V BCD, or Bipolar-CMOS-DMOS, power management process. AC direct LED driver ICs replace AC-DC converters or SMPS and controls power without the use of large capacitors and inductors over a range of AC input voltages.TowerJazz’s 700V BCD process provides a specialized device and design environment that is especially suited to LED lighting but also applicable to AC to DC converters as well as gate drivers for MOSFETs and IGBTs in applications such as electrical motors. This technology combines 6.5V, 16V and 26V CMOS for digital, analog and gate control blocks with 700V JFET, 450V and 700V NLDMOS for robust handling of 110v and 220V AC directly while maintaining a very low total layer-count and very good Rdson resulting in products with high performance and small die size.
