Dual N-Channel MOSFET Driver for ATX and SMPS Power Supplies: The NCP4330
, planned for release in Q3 2005 provides drive outputs for series FETs and free-wheeling synchronous FETs, to deliver higher efficiency compared to silicon rectifiers. It is the industry’s first post-regulator to provide synchronous FET drives. The device offers an efficient means of deriving 3.3 V or other outputs from the 5 V secondary, while not requiring additional windings or terminals on the power supply’s power transformer. The secondary AC signal directly feeds the NCP4330 to minimize power dissipation, while reducing the circuit’s part count. The device allows soft switching, thereby allowing efficient higher frequency operation. It is ideal for power supplies operating at frequencies up to 400 kHz and integrates under voltage lockointegrates under voltage lockout and thermal shutdown for rugged designs. The NCP4330DR2 will be offered in the SOIC-8 package, and budgetary pricing is $0.90 per unit in 1,000 unit quantities. Production is planned for Q3 2005.
