ON Semiconductor introduces next- gen HFSEPIC/boost controller for automotive apps

摘要

ON Semiconductor, 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.
