SEPIC/Boost Controller targets automotive applications.
September 21, 2012 -
With fixed switching frequency of 2 MHz, Model NCV898031 covers input voltage range of 3.2–40 V, and uses peak current mode control with internal slope compensation. Adjustable output, non-synchronous unit has built-in regulator that supplies charge to gate driver, plus 1.2 V ±2% reference voltage. Operating from -40 to 150°C, AEC-qualified device can cope with 45 V load dump. IC includes internally set soft start, under-voltage lockout, cycle-by-cycle current limiting, and thermal shutdown.

ON Semiconductor Introduces Next Generation High Frequency SEPIC/Boost Controller for Automotive Applications
Advanced, highly integrated device reduces cost of implementing power systems and saves board space
PHOENIX, Ariz. – ON Semiconductor (Nasdaq: ONNN), a premier supplier of high performance silicon solutions for energy efficient electronics, has released the NCV898031, an adjustable output non-synchronous single-ended primary-inductor converter (SEPIC)/boost controller, targeted for use in automotive applications. With a fixed switching frequency of 2 megahertz (MHz), the NCV898031 almost doubles the frequency performance offered by most competing devices on the market.
Covering a wide input voltage range of 3.2 volts (V) to 40 V, the controller uses peak current mode control with internal slope compensation. It has a built-in regulator that supplies charge to the gate driver, plus a 1.2 V ±2% reference voltage. Protection features include internally-set soft-start, under-voltage lockout, cycle-by-cycle current limiting and thermal shutdown. The AEC-qualified NCV898031 can cope with a 45 V load dump and has an operational temperature range of -40 °C to 150 °C. In addition, its low sleep-mode current of typically 10 microamperes (µA) helps to keep the total ignition off quiescent current budget to a minimum.
The higher frequency operation of this device allows it to be used with smaller and lower cost inductors and output capacitors, thereby lowering the overall cost and taking up less PCB real estate. Thanks to its protection mechanisms and wide voltage range, it is highly optimized for use in automotive applications, such as instrumentation clusters and infotainment systems.
“The enhanced frequency performance exhibited by the NCV898031 will be of great benefit to design engineers as they look to curb costs and better utilize available space, allowing smaller, less expensive passive components to be specified,” said Jim Alvernaz, ON Semiconductor director of automotive products. “In addition, its low quiescent current level will help to meet the demanding ignition-off requirements now being expected within the automotive industry.”
Packaging and Pricing
The NCV898031 is supplied in a RoHS-compliant SOIC-8 package and is priced at $1.02 USD for 2500 unit quantities.
