ON Semiconductor Wins “Top 10 DC-DC 2009” Award from Electronic Products China for NCP1034 High Voltage PWM Controller   Chinese

The NCP1034 is designed for high performance synchronous buck DC-DC applications

NCP1034 High Voltage PWM Controller

BEIJING, China Sept. 21, 2009 – ON Semiconductor (Nasdaq: ONNN), a leading global supplier of high performance, energy efficient, silicon solutions, today announced that it has been named a winner in Electronic Product China (EPC)’s “Top 10 DC-DC Awards 2009” for its NCP1034 high voltage PWM controller. This is the seventh consecutive year that ON Semiconductor has won the award.

Products honored with this award bear innovative designs, help realize significant technology improvement, or make great achievement in price-performance ratio. The NCP1034 is a flexible synchronous pulse width modulation (PWM) controller designed to operate from wide input supply voltage range of up to 100 volts (V), making it suitable for +48 V, +60 V and +100 V power supplies. The device also provides a 1 ampere (A) gate drive and is capable of producing output voltage of as low as 1.25 V.

“The NCP1034 is designed for high performance synchronous buck DC-DC applications with wide input voltages of up to 100 V,” said the judging panel. “Its synchronization feature allows the switching frequency to be set by an external source or output a synchronization signal to multiple NCP1034 controllers.”

“It’s really a significant honor to receive this award for the seventh consecutive year,” said Hemen Cheng, ON Semiconductor global power supply segment sales and marketing director for ON Semiconductor’s Computing and Consumer Products Group.  “It further demonstrates ON Semiconductor’s continuous efforts on innovation and cost effectiveness. The NCP1034 has the benefits of driving high efficiency FETs and providing fixed frequency for one or more devices. It has a wide range of application areas, from consumer electronics including LED backlighting for LCD TVs, to automotive, computing and industrial.”

The NCP1034 drives a pair of external N-channel MOSFETs using a programmable switching frequency of up to 500 kilohertz (kHz) which allows flexibility to tune the operation of the IC to meet system level requirements. The output voltage can be precisely regulated using the internal 1.25 V reference voltage for low voltage applications. Protection against electrical faults, such as under voltage lockout and hiccup current limit, is provided to give required system level security in the event of a fault.

Other features include external frequency adjustment, programmable soft-start, programmable over current protection and hiccup current limit using MOSFET RDS(on).
