in Consumer Electronics
In a move to advance its portfolio of power management integrated circuits Integrated circuits
Miniature electronic circuits produced within and upon a single semiconductor crystal, usually silicon. Integrated circuits range in complexity from simple logic circuits and amplifiers, about 1/20 in. (1. (ICs), ON Semiconductor (Nasdaq:ONNN) today introduced the NCP1205 -- an innovative Pulse Width pulse width Pulse duration Cardiac pacing The duration of a pacing pulse in msecs Modulator Modulator
Any device or circuit by means of which a desired signal is impressed upon a higher-frequency periodic wave known as a carrier. The process is called modulation. The modulator may vary the amplitude, frequency, or phase of the carrier. (PWM (Pulse Width Modulation) A modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. Like its fixed-width pulse density modulation (PDM) cousin, the output switching transistor is on more of the time for a ) current-mode controller for high-voltage and off-line power conversion applications.
The NCP1205 specifically targets high-efficiency and low-power, stand-by applications requiring quiet ElectroMagnetic Interference See EMI. (EMI (ElectroMagnetic Interference) An electrical disturbance in a system due to natural phenomena, low-frequency waves from electromechanical devices or high-frequency waves (RFI) from chips and other electronic devices. Allowable limits are governed by the FCC. ). A typical 30-watt SWITCHMODE(TM) power supply built with the NCP1205, consumes less than 150 milliwatts at high line (240Vac) and no load.
These performance levels comply with stringent energy saving regulatory guidelines including Energy Star(R), Blue Angel and the International Energy Agency (IEA IEA International Energy Agency
IEA International Environmental Agreements
IEA International Association for the Evaluation of Educational Achievement
IEA Institute of Economic Affairs
IEA Inferred from Electronic Annotation
IEA International Ergonomics Association ) recommendations.
The NCP1205 operates in true Quasi-Resonant (QR) valley switching mode and reduces its switching frequency when the output power demand decreases. These features naturally reduce EMI and turn-on losses, while dramatically improving power supply efficiency when in stand-by mode.
Frequency reduction takes place without creating a "singing" transformer. Designers can then reduce board costs by implementing inexpensive magnetic components -- free of noise problems.
The high efficiency and quiet EMI behavior of the NCP1205 make it ideal for power conversion in consumer electronics and Internet appliances. Such applications include cable or satellite TV boxes, game consoles, laptop computer adapters, open-frame power supplies, stand-by power supplies, lightweight battery chargers, DVD players and any space constrained power supply application.
NCP1205 SPICE models are capable of transient cycle-by-cycle simulation and are available online. These ready-to-use SPICE models can be downloaded from ON Semiconductor's Web site at http://www.onsemi.com/ncp1205.
Packaging & Pricing
The NCP1205 series is available in PDIP-8 and PDIP-14 packages priced at $0.65 for 10,000 unit quantities.
