开关电源
应用概述
开关电源是利用现代电力电子技术，控制开关管开通和关断的时间比率，维持稳定输出电压的一种电源，开关电源一般由脉冲宽度调制（PWM）控制IC和MOSFET构成。随着电力电子技术的发展和创新，使得开关电源技术也在不断地创新。目前，开关电源以小型、轻量和高效率的特点被广泛应用几乎所有的电子设备，是当今电子信息产业飞速发展不可缺少的一种电源方式。
针对开关电源领域，芯长征推出了一系列高校及可靠的VD MOS系列和SJ MOS系列。芯长征自主研发的高压SJ MOS采用先进的多层外延技术，实现了极低导通电阻RDSON和FOM优值(RDSON*Qg)，为客户的高效率、高可靠性需求提供了良好的选型条件。
