AnalogicTech's High Voltage Step-down Controller Maximizes 12V Adapter Design Flexibility Use of External MOSFETs Supports Both Synchronous and Non-Sy

Advanced Analogic Technologies, Inc. (AnalogicTech(TM)) (AATI 2.77, -0.14, -4.8%) , a developer of power management integrated circuits, announced today the AAT1185, a single output, step-down controller capable of providing high efficiency power conversion for lower cost 12V adapters. Fabricated in AnalogicTech's innovative Modular BCD process, the new controller maximizes design versatility by offering both high and low-side pins to drive a wide variety of external N-Channel MOSFETs. Moreover, by supporting both fully synchronous and non-synchronous operation, the new device allows designers to develop solutions for such disparate applications as wireless LANs, DSL and cable modems, notebook computers and set-top boxes with a broad range of performance and power efficiency levels.

"Given the diversity of 12V adapter applications today, designers need a high degree of flexibility to optimize the solution for their particular system," says CJ Zhang, product line vice president at AnalogicTech. "By providing low and high side pins to drive external MOSFETs instead of embedding the MOSFETs directly into the IC, the AAT1185 controller gives designers the option of building lower-cost, non-synchronous solutions using a Schottky diode on the load side switch or building high efficiency synchronous solutions using any of a wide array of power MOSFETs."Continued...
