ON Semiconductor Addresses Modern Power Design Challenges at Applied Power
Electronics Conference 2013
Cutting-edge digital AC-DC PWM controllers, motor drivers and IGBTs to be
demonstrated by the company at industry’s premier power electronics show
LONG BEACH, Calif. -- March 18, 2013
ON Semiconductor (Nasdaq: ONNN), driving innovation in energy efficiency, will
showcase its latest power efficient product advances at APEC 2013, March
17-21, 2013, in Long Beach, California. The new devices are designed for
boosting performance and simplifying the design of offline power supplies, AC
lighting infrastructure and motor control systems.
Targeted for high efficiency, compact, switch-mode power supplies for power
adaptors, the NCP1937 is a quasi-resonant (QR) flyback controller device with
power factor correction (PFC). This is the first AC-DC device utilizing a
hybrid digital core architecture enabling higher efficiency, increased
flexibility and easier system design implementation. The device incorporates
all the features necessary for building a robust and compact PFC stage in
combination with a QR flyback stage, while minimizing the number of external
components. The quasi-resonant current-mode flyback stage features a
proprietary valley-lockout circuitry, ensuring stable valley switching. It has
wide voltage range spanning 9 volts (V) to 30 V, plus built-in over-voltage
protection, and a skip mode operation which enables higher efficiency in light
load conditions. The NCP1937 will be demonstrated in an 85 watt (W) Notebook
Adapter showcasing the industry’s leading <10 milliWatt (mW) no load standby
The NCP1255/NCP1254 is a fixed frequency PWM controller designed for
applications requiring peak power capability. Offered in SOIC-8 and TSOP-6
packages, it operates with a fixed 65 kilohertz (kHz) switching frequency with
the ability to scale the frequency up to 130 kHz based on output load
requirements. In light load conditions with the power on the secondary side
decreasing, the IC automatically folds back its switching frequency to a
minimum level (26 kHz). The inclusion of adjustable over-power protection and
adjustable brown-out protection functions make this device ideal for products
requiring peak-power capabilities such as printers and ultrabooks. The NCP1255
will be demonstrated in a 15 W nominal 55 W peak power printer adapter.
For LED power supply applications, the high functional integration of the
NCL30081 PWM controller IC minimizes the number of external components
required for AC powered LED lighting designs. It operates in a quasi-resonant
mode to enhance overall efficiency and provides precision regulation of the
LED current from the primary side. Dispensing with the need for secondary side
feedback control, as well as the associated optocoupler and biasing circuitry,
the device is specifically intended for very compact space efficient designs
utilizing either flyback or buck-boost topologies. It supports step dimming by
monitoring the AC line and detecting when the line has been toggled on-off-on
by the user to reduce the light intensity in five steps down to five percent
dimming. The NCL30081 will be demonstrating the step dimming functionality and
compact system solution in a standard GU10 bulb design.
The NSIC2020 is a linear constant current regulator based on Self-Biased
Transistor (SBT) technology. Because these devices do not require the
specification of any external components, they can serve as either high or low
side regulators, thus offering a streamlined solution that makes the
development process more straight forward and maximizes design flexibility.
This compact SMB packaged device is capable of regulating current over a wide
voltage range (from 0 V to 120 V). Its negative temperature coefficient
enables protection of LED emitters from thermal runaway at extreme voltages
Also on display at the ON Semiconductor booth will be theLV8702V, a high
efficiency stepper motor driver IC housed in a compact SSOP package and
targeted at office automation equipment applications (multi-function printers,
copiers, scanners, etc.). It is capable of dramatically lowering no-load power
consumption and peak motor current, thereby maximizing energy efficiency in
system designs. The company’s latest 1200 V IGBTs using trench field stop
topologies and 40 ampere (A) current ratings will be also be featured.
Offering both low on state voltage and minimal switching loss, the IGBT is
well suited for motor drive control and other hard switching applications.
