ST boosts bipolar power transistor current by 50 Percent
Product News  
2/27/2011   Post a comment
The 3STR1630 NPN transistor from STMicroelectronics is the first member in a new family of high-performance bipolar power transistors manufactured using a new low-voltage planar technology. This technology incorporates a double-metal process that allows the cell density to be almost doubled without requiring the use of sophisticated photolithography equipment. In addition to increasing the current capability by about 50 percent for the same die size, the double-metal process enables transistors

Fairchild’s FAN6204 SR controller for flyback and forward topologies has multiple operating modes
Product News  
2/21/2011   Post a comment
Fairchild Semiconductor's FAN6204 is a secondary-side synchronous rectification (SR) controller designed to meet increased power efficiency demands and regulatory standards for desktop PCs, All-in-One (AIO) PCs and notebook adaptors. Using a proprietary, innovative linear prediction timing-control technique not limited to the RDS(ON) of the SR MOSFET, the FAN6204 is suitable for fixed frequency or quasi-resonant (QR) flyback converters and discontinuous or continuous conduction mode (DCM and CCM
