Applied Power Electronics Conference (APEC) – Booth 407 – ON
Semiconductor (Nasdaq: ONNN),
driving energy efficient innovations, will be showcasing some of its
latest advances in power management technology at APEC, including a new
LLC current-mode power supply for computers and LED TVs, significant
developments in GaN, and a sensor-less motor driver controller.
Current-Mode LLC Power Supply
One of the demonstrations will include the industry’s first current-mode
LLC controller, the NCP1399, highlighting the safety features and
benefits inherent to a current-mode control approach. The power supply
reference design will incorporate the NCP1399 along with ON
Semiconductor’s NCP4810
X2 capacitor discharger, NCP1602
power factor controller, and NCP4305
synchronous rectification controller. This system solution is
predominantly aimed at power supplies for all-in-one computers and large
LED TVs, as well as ultra-high density power adapters. It is capable of
achieving markedly higher performance, lower standby power and higher
power conversion efficiency levels than would be possible using
competitive devices. The current-mode control architecture of the
NCP1399 is the heart of the power supply reference design bringing
built-in protection features, faster transient response and light load
efficiency enhancements. The NCP4305 provides improved efficiency with a
large 8 A driver and built-in light load detection.
Converter with GaN High-Electron-Mobility Transistors (HEMTs)
A two-stage converter demonstrating the latest high-efficiency results
obtainable with GaN will also be featured at APEC. This 240 watt (W)
supply achieves 95 percent peak efficiency with the NCP1397
LLC controller, NCP1654
power factor correction controller, and TPH3202PS or NTP8G202N
GaN transistor switching devices. The board utilizes GaN HEMTs in
both the PFC stage and in the primary side of the LLC stage.
Automotive Motor Driver
The motor driver demonstration showcases a next generation software-less
automotive motor driver solution, LV8907. On-chip intelligent
sensor-less commutation logic enables LV8907 to drive a brushless DC
(BLDC) motor without any position sensor, thereby reducing the solution
cost and footprint. This software-less solution with on-chip
configuration registers can be customized for a wide range of motor and
load combinations using an easy-to-use and free graphical user interface
(GUI) utility from ON Semiconductor. LV8907 with pre-loaded
configuration registers can drive the motor in a stand-alone mode
without an external system controller. With an integrated LIN
transceiver, LV8907 can also deliver a LIN-based advanced motor drive
solution using a small and low cost companion controller that is
required only for LIN management tasks.
Additionally, ON Semiconductor technical experts will be giving Professional
Education Seminars at APEC 2015 as part of the conference agenda:
-
Christophe Basso, application engineering director at ON
Semiconductor, will present a seminar on "Practical
Implementation of Loop Control in Power Converters" (March 16)
-
Roger Stout, research scientist at ON Semiconductor, will
present a seminar on "Power Electronics System Thermal Design"
(March 16)
